Introduction to the FamilySearch Help Center

 

https://youtu.be/StO6PCVtEpw?si=mL1IINrl1MlqDKr6

Navigating a platform as expansive as FamilySearch can feel daunting, but the built-in Help Center is designed to guide researchers through every stage of their family history journey. In this instructional presentation from the BYU Library Family History Center, I provide a clear, comprehensive walkthrough of the Help Center’s vast features and resources. Viewers will discover how to access self-paced learning modules, search thousands of instructional articles, and utilize tailored research pathways designed for both beginners and seasoned genealogists.  

Beyond basic search tools, this video explores deeper support layers, including the Learning Center’s country-specific research guides, technical skill lessons, and the interactive FamilySearch Community. Tanner also outlines key support avenues—such as specialized helper tools for consultants and direct contact options with FamilySearch specialists—giving you the skills and confidence to solve tricky genealogical problems and make continuous progress on your family tree. 

The BYU Library Family History Center classes will be discontinued after August 30, 2026. The videos here on YouTube and on youtube.com will remain active for an unspecified period of time. For more rare information, see the link below.

MyHeritage adds Y-DNA to trace your paternal line back

https://blog.myheritage.com/2026/08/new-on-myheritage-trace-your-paternal-line-back-thousands-of-years-with-y-dna/

For years, genetic genealogy platforms have largely separated autosomal testing—used for finding cousins across recent generations—from direct-line Y-DNA testing, which traces direct paternal lineages deep into human history. MyHeritage has bridged this divide by integrating baseline Y-DNA haplogroup reports directly into its existing testing database. Existing male MyHeritage DNA customers and eligible raw data uploads can generate baseline Y-DNA results without submitting a new sample. However, access to the reports is only included at no additional charge for users holding an active MyHeritage Complete or Omni plan. The MyHeritage Complete plan presently has a promotional first year price of $199 and then an annual renewal price of $299. The Omni Plan's promotional first year price is $239 and then $399 thereafter.

The Omni Plan is MyHeritage's all-inclusive bundle. It adds access to external properties owned by MyHeritage, specifically historical newspapers via OldNews.com, collaborative tree tools on Geni Pro, and the entire library of 2,000+ educational sessions on FamilyTreeWebinars.com.  

Because the analysis relies on the limited Y-chromosome single-nucleotide polymorphisms (SNPs) captured during standard microarray autosomal testing, the resulting haplogroups represent broad, ancestral branches—often dating back to the Middle Ages or earlier. For researchers seeking high-resolution matching and sub-clade identification within recent genealogical timeframes (the past several hundred years), MyHeritage offers an integrated pathway to upgrade directly to FamilyTreeDNA’s Big Y-700 next-generation sequencing test. The FamilyTreeDNA Big Y-700 test is presently $399. These prices may change. 

The newly introduced feature extracts Y-chromosome markers already present in the raw data of biological male test-takers, eliminating the need to submit a new sample. Developed in partnership with FamilyTreeDNA, the analysis assigns qualifying users a foundational Y haplogroup and places their lineage on the broader human paternal phylogenetic tree.

Once activated through account settings, the tool provides five core reports:

• Haplogroup Story: An overview of the lineage’s classification, accompanied by historical context, a branch diagram, and badges outlining key lineage characteristics.

• Migration Map: A geographical model plotting estimated ancestral migration paths originating from early human populations in Africa, including divergence points for parent and sibling branches.

• Notable and Ancient Connections: Side-by-side historical comparisons linking a user’s lineage to notable historical figures and ancient DNA samples recovered from archaeological excavation sites.

• Country Frequency: A distribution breakdown based on comparative testing databases and academic studies, illustrating where specific haplogroups are most frequently reported worldwide.

These feature may change from the first introduced features. 

Regarding data handling, MyHeritage confirmed that the underlying computational models are licensed from FamilyTreeDNA but executed entirely within the MyHeritage infrastructure; user raw genetic data is not transferred to third-party databases during processing.

Access to the Y-DNA reporting suite is available immediately to male test-takers with active MyHeritage Complete or Omni subscriptions. Female users wishing to explore their direct paternal lineage will need to test a qualifying direct male relative, such as a father, brother, or paternal uncle.

The Changing World of AI -- Tokens and Users

 

If you are wondering how to compare the various AI websites that have sprouted up over the last four years or so, there is a common way to do this. The most common comparison involves the amount of information, and to some extent the amount of detail and helpfulness of AI websites' responses. The comparisons are based on the total amount of information the AI chatbots have available. Tokens are the basic units of data (pieces of words, characters, or syllables) that the model processes at one time for input (your prompt) and output (its answer). Roughly, 1,000 tokens equal about 750 words.  See What are tokens and how to count them? 

The number of tokens available makes a substantial difference across three main areas: the context window (input/working memory), the output limit (generation size), and cost/speed. The following explanations came from Google Gemini. 

Context Window (Working Memory): The maximum input token limit determines how much information an AI can analyze at once. A small window (e.g., 4k–8k tokens) limits you to brief queries, while a massive window (e.g., 128k to 1M+ tokens) allows you to feed in entire books, hundreds of pages of legal transcripts, extensive codebases, or complex multi-document archives without the AI "forgetting" earlier context.

Output Generation Limits: The maximum output token capacity dictates how long a single response can be. If an AI has a 4,000-token output limit, it cannot generate a complete 30-page document in a single pass; it will cut off mid-sentence once that threshold is reached.

Cost and Billing (APIs): For developers and API users, token volume directly drives pricing. Every token sent (prompt) and received (completion) is metered. A larger token budget means higher processing costs.

Back to Me:

What this means to a user is that the more complicated the requests that are made to the AI, the greater the cost. But the AI websites have a tiered subscription cost based on the amount of information processed or tokens used.

A comparison of the value of the AI website subscription could be made using a cost/token breakdown. However, consumer subscriptions are usually based on a flat monthly rate with usage caps. But comparisons can be made through the cost versus rate caps. High-end users work through an Application Programming Interface or API and are charged based on input and output tokens. Here is a table that Gemini generated showing the rate caps, reset windows, and soft limits of the most popular websites. 

Provider / Plan ($20/mo)	Standard Chat Rate Cap	Reasoning / Deep Thought Limits	Context Window on Web	What Happens When Capped?
ChatGPT Plus (OpenAI)	~150–160 messages every 3 rolling hours	Strict separate allowances for dedicated reasoning modes (e.g., weekly/daily limits)	~32k to 128k tokens depending on model	Automatically throttles down to a lighter "mini" model until the 3-hour window resets.
Gemini Advanced (Google)	High soft cap (rarely hits a hard message wall in regular chat)	Dynamic limits based on server load when using extended thinking/analysis	1M to 2M tokens (ingests massive documents/books directly in the web UI)	Temporary slowdown / cooldown notice; drops to standard Flash models if server capacity is tight.
Claude Pro (Anthropic)	Dynamic 5-hour rolling pool (~45 messages for long threads; more for short chats)	"Thinking Mode" burns through your 5-hour budget significantly faster	200k to 1M tokens	Hard block until the 5-hour rolling reset window expires.
Microsoft Copilot Pro	~100–300 turns/day (integrated across 365 and web)	"Think Deeper" runs at slower speeds during peak hours	Typically capped around 32k–128k tokens	Slows to standard processing speed or caps conversation turn depth.

See for example: Claude pricing in 2026: every plan, API rate, and what it actually costs, and Cost of building and deploying AI models in Agent Platform.

Again, from Gemini:

Core Mechanics That Dictate Limits

Conversation Depth Depletion (Claude): Anthropic calculates limits based on total token volume sent. Because Claude resends the entire conversation history with every new message, long conversations or large file uploads consume your 5-hour quota much faster than starting fresh chats. 

Fixed Time Windows (ChatGPT): OpenAI uses rolling 3-hour windows for general chat, making it predictable for burst work, but caps reasoning models with much stricter weekly or daily quotas.

Context Capacity (Gemini): Gemini offers the largest context window for consumers on the web (up to 2 million tokens), allowing entire archives or hours of video to be uploaded in a single prompt without immediately triggering rate limits.

Back to Me:

If you are a casual user of any of these websites using the free versions, it is possible that you have not encountered any data limitations. But a genealogist, for example, can run into an immediate token limit by asking one of the AI websites to transcribe or explain a long, difficult document. What is disturbing is that the lack of a token buffer can cause the AI chatbot to hallucinate or make up information. See Why Language Models Hallucinate.

If you doubt the accuracy of any of the AI output, I suggest you take time to learn how to ask questions and generate prompts. See How to Improve Any Prompt.

Another suggestion is that you spend time using your AI to explain the terms and conclusions of this blog post. 

A Major Update of Keep or throw away: the challenge of genealogical documents and photos

 

Over the past few weeks, we have spent a considerable amount of time working through tens of thousands of documents and photos and trying to reduce the number of documents and photos we save to a manageable one or two boxes for my and the same number for my wife. This post is a sequel to the earlier post called "Keep or Throw Away: The Challenge of Genealogical Documents and Photos." The key to this reduction is that thousands of the original documents were scanned and now reside on three large (16 - 22 TB) hard drives. One of those essentially duplicate hard drives in addition to my main computer are also backed up to the internet on https://www.backblaze.com/. Some of the documents, such as original journals, will also be offered to the BYU Harold B. Lee Library Special Collections. 

There are still some major decisions that need to be made. The main issue deals with original photos and original handwritten letters. All the photos can be digitized, and all of the handwritten letters can also be digitized. The issue is: which of these two categories of oath should be preserved as physical documents? 

Even when we are able to make the decisions and have decided on the original physical documents to be preserved, including letters, photos, certificates, and other historical artifacts, we will still need to work through the thousands and thousands of digital files. I certainly realize that most genealogists are not confronted with either the diversity or quantity of documents that were given to me over the last, going on, 45 years. 

One of the main issues is that, over the time period that we have been accumulating these documents, I have had virtually no contact from any of my vast number of relatives asking if I have the documents and if they are available for review. One tactic my wife has used is to take piles of the documents to family gatherings and offer to let anyone at the gathering take some of the original documents. Of course, all the documents offered have already been digitized also. 

Over the next few weeks, I intend to highlight and explain some of the interesting documents I have "discovered" while working through the piles. Here is an initial. example.

 this is a graduation certificate for my grandfather, and it is about three feet square.

Stay tuned for further developments.

Computer Generated Family Trees Ignore the Heart and Soul of Genealogy

 

https://www.familysearch.org/en/search/genealogies/submissions?f.collectionId=10000130

Just because you can do something does not make it a good idea. There is no question that a computer using an AI program could examine a record and create a family tree from the record. In fact, here is an example of an AI prompt using Google Gemini to do exactly that. 

Here is the record. 

Sahuaripa (Sonora). Registro Civil

Sonoyta (Sonora). Registro Civil

Tepache (Sonora). Registro Civil

Here is a suggested prompt generated using Google Gemini. 

Act as an expert Mexican genealogist and master paleographer specializing in early colonial Spanish records. You strictly adhere to the Genealogical Proof Standard (GPS) and execute a reasonably exhaustive search methodology across Mexican archives (including Catholic parish registers, información matrimonial, civil records, notary protocols, land grants, and Inquisition/governmental administrative files).

Paleographical & Technical Directives:

• Script & Hand Analysis: Identify and adapt to specific colonial hands—including Cortesana, Procesal, Procesal encadenada, and transitional hands (16th–18th centuries).

• Contractions & Abbreviations: Systematically resolve historical abbreviations, suspension marks, and sigla. Expand abbreviated names, words, and titles in brackets [ ] within transcriptions while preserving original spellings in literal passes.

• Orthography & Phonetics: Maintain historical spelling variants (e.g., interchangeability of b/v/u, c/z/ç/s, i/y/j, silent or added h) while accurately interpreting intended proper nouns and surnames.

Transcription Conventions for Damaged or Defective Manuscripts:

Apply standard diplomatic-paleographic bracket conventions to denote document damage, ink bleed-through (traspaso de tinta), fading, or torn margins:

• [word]: Expansion of an abbreviation or scribal contraction (e.g., Fran[cis]co).

• [text?]: Conjectural or probable reading of faded, obscured, or damaged text.

• [...]: Illegible or destroyed text. Indicate approximate length when possible (e.g., [... 2-3 words]).

• [sic]: Confirmed scribal error or unusual spelling in the original manuscript.

• <text>: Text inserted by the scribe above the line (interlineado) or in the margin.

• [strikethrough] or [crossed out: text]: Text canceled or erased by the original writer.

• [damage: reason]: Explicit note explaining physical obstruction (e.g., [damage: hole in folio], [damage: heavy ink bleed], or [damage: torn margin]).

Tasks:

1. Dual Transcription & Translation:

   • Literal Diplomatic Transcription: Provide a verbatim transcription strictly preserving line breaks, original spelling, unexpanded abbreviations, and the bracketed damage conventions above.

   • Normalized Text & English Translation: Provide a modernized, expanded version alongside a precise, context-aware English translation that accounts for missing text inferred through formulaic record patterns.

2. Data & Context Extraction: Extract all explicit and implicit genealogical facts for every individual mentioned, including full names, relationships, dates, jurisdictions (doctrina, jurisdicción, parroquia), witnesses, godparents (padrinos/compadres), occupations, and social/ethnic status descriptors (casta, vecindad, originario de, titles such as Don/Doña).

3. Structured Relationship Table: Construct a clear, structured table/spreadsheet detailing the family connections established by the document with the following columns:

   • Individual's Name (Literal & Normalized)

   • Role / Position in Record (e.g., Subject, Father, Paternal Grandmother, Godparent, Witness, Notary)

   • Relationship to Subject

   • Stated/Estimated Event Date & Location

   • Casta / Status / Origin

   • Paleographic & Condition Notes (e.g., reading uncertainty due to bleed-through, reconstructed from formulaic context)

4. Genealogical & Evidence Analysis: Evaluate source reliability (primary vs. secondary), evidence type (direct vs. indirect), and information quality under the GPS. Flag name variations, conflicting evidence, or missing linkages caused by document damage, and suggest specific archival next steps (e.g., checking duplicate parish books or local notary registers).

Here is the analysis after applying the prompt:

Document Analysis: Civil Registration Death Records (Tepache, Sonora, 1941)

These entries come from a pre-printed form register of the Civil Registry (Registro Civil) in the Municipality of Tepache, State of Sonora, Mexico, dated July 1941. The script is a 20th-century modern cursive hand with standard abbreviations and minor printed form overlays.

4. Genealogical & Evidence Analysis (GPS Standard)

Source Reliability & Information Quality

• Source: Primary official civil registry register (Registro Civil de Tepache, Sonora). Original register pages 8 and 9.
  
  
• Evidence Type: Direct evidence for the dates, ages, causes of death, and paternal relationships of both deceased infants.
  
  
• Informant Accuracy: High for basic parental and event details (fathers Ramón Ayón and Loreto Blanco personally reported their daughters' deaths within 24 hours).
  
  

Critical Observations & Scribal Errors

1. Acta 16 (Margarita Ayón):
   
   
   • Scribal Error: The clerk crossed out pre-printed/handwritten entries regarding raza (race/casta), reflecting post-revolutionary legal transitions removing race categories from civil registration.
     
     
   • Maternal Identity: Refugio Velarde is listed as the head of household or mother ("en su domicilio de su casa de Refugio Velarde, su hija...").
     
     
2. Acta 17 (Antonia Blanco):
   
   
   • Copying Slip (Lapsus Calami): In line 8-9 of Acta 17, the clerk mistakenly began writing the subject's name from the adjacent record (Acta 16) as "Margarita [Ayón]" before striking it out. The header clearly establishes the child's correct name as Antonia Blanco.
     
     
   • Cause of Death Terminology: "Vaso y Dolor" refers to a traditional diagnosis for abdominal/splenetic disease or severe infant colic.
     
     

Archival & Research Recommendations

• Parish Registers: Search the local Catholic church registers (Parroquia de San Joaquín de Tepache) for the baptismal records of Margarita Ayón (born ~June 1941) and Antonia Blanco (born ~June 1941) to confirm mothers' full names, maternal grandparents, and godparents.
  
  
• Marriage Records: Search civil and parish marriage registers for Ramón Ayón & Refugio Velarde, as well as Loreto Blanco and his wife (not named in Acta 17), between 1925 and 1941 in Tepache, Moctezuma, or surrounding Sonoran municipalities.
  
  

 Do you happen to read Spanish? Can you look at the original record and tell whether or not the information given by Google Gemini is correct?  The only way that I could possibly rely on this transcription and analysis would be if I could actually read the document for myself, which I can do. The information provided is extensive and very convincing, and it is obviously more convenient. Absent the knowledge about the record and the ability to translate the information from Spanish into English, it would be impossible for an individual to determine whether or not all the information provided by Gemini was accurate. There is no trade-off.
