Research Mistakes – Ignoring Records That Don’t Fit Your Theory

The record that proves your theory wrong may be the one that leads you to the right ancestor.

Every genealogist develops theories while researching. The problem begins when we accept only the records that support those theories and quietly ignore those that do not.

Conflicting records are not inconveniences—they are opportunities to discover a more accurate family history. Sometimes the record that doesn’t fit is the very clue that solves the mystery.

Why This Mistake Happens

Once we believe we have found the correct ancestor, it is natural to interpret new information in a way that confirms our conclusion.

Researchers often become invested in a particular family connection, birthplace, or timeline. When a record disagrees with that conclusion, it is tempting to dismiss it as an error rather than investigate why it differs.

In reality, conflicting evidence often reveals that we have overlooked another person, misunderstood a relationship, or made an incorrect assumption earlier in our research.

Common Warning Signs

• You ignore records that disagree with your conclusions.
• You assume conflicting information must be incorrect.
• You stop searching after finding records that support your theory.
• You explain away inconsistencies instead of investigating them.
• You avoid comparing conflicting records side by side.
• You rely on one type of record while ignoring others.
• You become reluctant to change your conclusions despite new evidence.
• You believe your original theory must be correct because you have invested so much time in it.

The Hidden Cost

Ignoring conflicting records can prevent you from discovering the truth.

You may:

• Research the wrong family for years.
• Miss the correct parents or spouse.
• Overlook important records.
• Build incorrect relationships.
• Fail to recognize that two people have been combined into one.
• Miss the evidence that finally solves the problem.

Every ignored record increases the risk that your conclusions become more difficult to correct.

A Better Way

Treat every conflicting record as a question that deserves an answer.

Instead of asking:

“Why is this record wrong?”

Ask:

“Why is this record different?”

Compare all available evidence.

Consider:

• Who created the record?
• When was it created?
• Who supplied the information?
• Which record is closest to the actual event?
• Can multiple records explain the discrepancy?

The goal is not to eliminate conflicting evidence, but to understand it.

Questions to Ask Yourself

• What records disagree with my conclusion?
• Have I honestly considered every piece of evidence?
• Could my original assumption be incorrect?
• Have I explained the conflict—or simply ignored it?
• What conclusion would I reach if I started from scratch today?

Key Takeaway

The strongest genealogy conclusions are built by considering all the evidence—not just the records that support an existing theory. When a record disagrees with your assumptions, resist the temptation to dismiss it. It may contain the clue that leads you to the correct answer.
