How to Evaluate Genealogy Evidence and Conflicting Records
Conflicting records are normal in genealogy. The work is not to erase the conflict, but to describe it clearly and decide what the evidence can and cannot support.

Expect disagreement
Genealogy records disagree because people made mistakes, informants guessed, officials misheard names, families moved, ages were rounded, and later memories changed details. A conflict is not proof that one source is useless. It is a signal that the evidence needs to be described more carefully.
Imagine a fictional ancestor, Ada Wilkes. One census suggests she was born in Ohio. A later death certificate says Pennsylvania. A granddaughter remembered “somewhere near Pittsburgh,” while a marriage record gives no birthplace at all. The answer may eventually be Pennsylvania, Ohio, a border county, or something more complicated. The important first step is not choosing a favorite. It is naming the conflict.
Identify what each source actually says
Start by extracting the information without adding interpretation.
Do not write:
Ada was definitely born in Pennsylvania.
Write:
Ada’s 1938 death certificate gives Pennsylvania as her birthplace. The informant was her son Charles.
Then add the census evidence separately:
The 1900 census entry for Ada’s household gives Ohio as her birthplace. The informant is not identified on the page.
Now you can see the evidence instead of a blended conclusion.
Ask who likely provided the information
Some records are close to an event. Others are created years later by someone who may not have known the answer. A birth record made near the time of birth may carry different weight than a death certificate where an adult child supplied a parent’s birthplace decades later.
This does not mean the later record is wrong. It means you should ask:
Who probably supplied this information?
Were they present for the event?
How much time had passed?
Was the detail central to the record’s purpose?
Could the clerk, enumerator, or transcriber have introduced an error?
The answer often changes how much confidence you place in a record.
Separate direct evidence from clues
Some evidence answers your question directly. If your question is “Where was Ada born?” a record that states a birthplace is direct evidence for that question.
Other evidence is indirect. A sibling’s birthplace, a nearby relative, a church membership, a migration route, or a repeated neighbor may not answer the question alone. Together, however, those clues can point toward a more supported conclusion.
Indirect evidence is powerful, but it should be handled with care. Label it as a clue until the pattern is strong enough to explain.
Keep the conflict visible
Do not delete the record that disagrees after you choose a working conclusion. Future researchers need to understand why the question was difficult and why one answer was preferred.
A useful evidence note might say:
Working conclusion: Ada Wilkes was probably born in western Pennsylvania. This is supported by the death certificate and the granddaughter’s memory. The 1900 census gives Ohio, so the conclusion remains open pending birth, church, or early residence records.
That note is honest. It gives a probable answer without pretending the conflict disappeared.
Look for independent support
One record can be wrong. Two records can repeat the same error. Stronger conclusions come from independent sources that were created for different reasons and still point in the same direction.
For Ada, you might look for:
a birth or baptism record
a marriage record naming birthplace or parents
a sibling’s record
a parent’s probate file
church membership records
county histories used cautiously
land, tax, or directory evidence
a census comparison across decades
The goal is not to collect everything forever. The goal is to gather enough independent evidence to explain why the conclusion is reasonable.
Use confidence language
Family-history writing becomes stronger when it uses confidence language. Try words such as:
confirmed
strongly supported
likely
possible
unresolved
disproved by later evidence
These words help your archive breathe. They show that the family story can include both warmth and care.
A calm evaluation checklist
For each source, ask:
What exact statement does this source make?
Who created the source?
Who supplied the information?
When was it created in relation to the event?
Is it original, copied, indexed, transcribed, or summarized?
Does it directly answer the question?
Does it agree or conflict with other evidence?
What conclusion, if any, is supported?
What still needs research?
You do not need to solve every conflict immediately. You only need to keep the trail clear enough that the next step makes sense.
Write a conflict note before choosing
When two records disagree, write a brief conflict note before you decide which one you believe. The act of writing slows the rush toward certainty.
For Ada Wilkes, a note might look like this:
Birthplace conflict: The 1900 census gives Ada’s birthplace as Ohio. Her 1938 death certificate gives Pennsylvania, with her son Charles as informant. A granddaughter remembered “near Pittsburgh,” but did not know whether that referred to Ada’s birthplace or childhood home. Working conclusion remains unresolved pending earlier records.
That kind of note does three things. It names the conflict. It identifies the informants where possible. It prevents a later reader from assuming you missed the disagreement.
Revisit evidence after new discoveries
Evidence evaluation is not a one-time event. A weak clue can become stronger when another independent source appears. A comfortable conclusion can become weaker when a new conflict surfaces.
Set a small review habit:
revisit unresolved conflicts after each new source
update confidence language when evidence changes
keep earlier notes instead of overwriting them silently
explain why a conclusion changed
This is especially important in family archives, where relatives may remember seeing an earlier version. A visible research trail makes revision feel like care, not contradiction.
The Roots Adventure approach
Roots Adventure treats evidence as part of the story’s integrity. A family archive can hold affection, memory, uncertainty, and documented proof side by side. The best archive is not the one that looks certain at every turn. It is the one that tells future relatives how each conclusion was reached.

One census record gives a snapshot. Comparing records across time can reveal migration, changing households, missing people, and new research questions.
