Here is a screenshot of two entries in the FamilySearch.org Family Tree. Garrard Mogan (#1) L7GZ-YBB b. 1755, d. 1786 is shown as the son of Doctor John Morgan GM8Y-L9D b. 1734, d. 1765. Doctor John Morgan's wife is Mary Woodson b. 1738, d. 1765. The genealogical research question is whether this relationship is adequately supported by valid historical records. The practical issue is whether Garrard could possibly be the son of Doctor John.
Garrard Morgan has 5 listed sources. Only one of the listed sources has any parent/child relationship information and that is a record showing the birth of his son, also Garrard Morgan (#2) LW1B-V31. This second Garrard Morgan #2 shares a source record with his father documenting his birth in St James Northam Parish, Goochland, Virginia, British Colonial America (this designation of British Colonial America is not universally accepted). But any reference to the Garrard #1's relationship to Doctor John Morgan is missing. Additionally, Dr. John is shown a being born in Shepardstown, Berkley, Virginia in 1734. While Garrard #1 is shown as born in Goochland, Colony of Virginia, British Colonial America.
My inclination is to look at the physical locations cited for both Garrard #1 and Doctor John, so I am going to craft a prompt for Google Gemini 3 telling it to consider the information that is there and decide if these to people are related and also to suggest future research options. If you have read this far, I suggest that you try out using this prompt with your own favorite chatbot. I have a subscription to Gemini 3 Pro, by the way.You may not know, but Google Gemini has access to all the information in the FamilySearch Family Tree except for living people and some restricted records.
I wrote a rather detailed prompt and then asked Gemini to examine the prompt and suggest changes. It suggested some substantial changes that I then incorporated. It is a good idea to let the chatbot tell you how to ask it questions.
Here is the prompt.
Role: Act as a professional genealogist and forensic investigator.
Objective: Evaluate the genealogical proof for the parent-child relationship between Garrard Morgan (L7GZ-YBB) / Elizabeth Milton (22J1-HM4) and their purported son, Doctor John Morgan (GM8Y-L9D) (husband of Mary Woodson GM8B-MS9).
Input Data: I have pasted the vital statistics, timeline, and source lists for these four individuals below.
Garrard Mogan (#1) L7GZ-YBB b. 1755, d. 1786 is shown as the son of Doctor John Morgan GM8Y-L9D b. 1734, d. 1765. Doctor John Morgan's wife is Mary Woodson b. 1738, d. 1765. The genealogical research question is whether this relationship is adequately supported by valid historical records. The practical issue is whether Garrard could possibly be the son of Doctor John.

Instructions:
Source Analysis: Critique the quality of the sources provided. Are they original or derivative? Do they provide direct evidence of birth/parentage, or only indirect evidence?
Data Consistency: Cross-reference the dates and locations. specificially look for:
Biological impossibility (e.g., mother's age at birth).
Chronological inconsistencies in location (e.g., being in two states at once).
Relationship Logic: Determine if the sources explicitly prove the link between Garrard/Elizabeth and John, or if the link is merely based on assumptions (like similar surnames in the same county).
Conclusion: Provide a verdict based on the Genealogical Proof Standard. Classify the relationship as "Proven," "Probable," "Possible," or "Disproven."\
There were other variations in the prompt suggested also. Yes, this type of detailed prompt might be necessary.
Here was the response:
Based on the genealogical data and constraints you provided, here is the forensic evaluation of the relationship between Garrard Morgan (#1) and Doctor John Morgan.
Genealogical Forensic Report
Subject: Verification of Parentage for Garrard Morgan (L7GZ-YBB)
Purported Parents: Doctor John Morgan (GM8Y-L9D) & Mary Woodson (GM8B-MS9)
Investigator Role: Professional Genealogist
1. Source Analysis
Direct Evidence Missing: The most critical finding in the source analysis is the absence of direct evidence. You noted that while Garrard Morgan (#1) has five sources attached, none of them name Doctor John Morgan as his father.
Misattribution of Evidence: The only source cited as proving a parent/child relationship actually applies to the next generation (Garrard #1’s son, Garrard #2). In professional genealogy, this is a common error known as "conflation of generations." A record proving Garrard #1 is a father does not prove who his father was.
Reliability: Without a will, bible record, deed of gift, or baptismal record explicitly naming "John Morgan" as the father of "Garrard Morgan," the current source list has zero probative value for the relationship in question.
2. Data Consistency & Biological Feasibility
3. Relationship Logic
The "Same Name" Assumption: The link appears to be based on an assumption rather than evidence. Users likely found a "Morgan" in Goochland and attached him to a prominent "Morgan" in Berkeley without proof.
Naming Patterns: The name "Garrard" is almost certainly a surname used as a given name (likely the mother’s maiden name). If Doctor John Morgan’s wife was truly Mary Woodson, the son should logically be named "Woodson Morgan" or named after the father/grandfather. The appearance of the name "Garrard" suggests Garrard #1's mother was likely a Garrard, not a Woodson.
4. Conclusion and Verdict
Verdict: UNSUBSTANTIATED (Likely Incorrect)
Reasoning:
No Proof: There is no direct evidence (wills, deeds, parish registers) linking the two men.
Geographic Conflict: The locations are inconsistent with prevailing migration patterns.
Onomastic Conflict: The name "Garrard" conflicts with the purported mother's surname "Woodson."
Summary: The relationship currently fails the Genealogical Proof Standard. The link appears to be a "path of least resistance" attachment common in online trees. Garrard Morgan (#1) is likely a member of a different Morgan line indigenous to the Goochland/Albemarle area, possibly connected to a Garrard family by marriage.
Next Step: Would you like me to help you brainstorm a search strategy to find Garrard Morgan's actual parents, perhaps by looking for "Morgan-Garrard" marriages in Goochland prior to 1755?
In following the subsequent instructions I have a possible solution to the inaccurate information. The conversation with Gemini 3 continued for several long pages. Yes, Gemini 3 can help.
My conclusion is that you may find adding Google Gemini 3 ( and subsequent updates) as your research companion. I might also suggest that you compare the results here with those of your current chatbot usage.
