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. 


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.
