Questions to Ask Before Accepting an Online Tree

Online family trees can provide valuable clues, but they often contain errors, assumptions, or incomplete information. Evaluating the reliability of a tree before accepting its conclusions is essential for accurate research.

Source and Evidence Questions

• Are sources provided – Does the tree cite records or documents?
• Are sources original or secondary – Are they based on actual records or other trees?
• Do multiple sources support the same fact – Is information consistent across records?
• Are citations specific – Can the source be located and verified?

Consistency and Accuracy

• Do dates make sense – Are birth, marriage, and death dates logical?
• Are locations consistent – Do places align with known migration patterns?
• Are relationships clearly supported – Is there evidence connecting family members?
• Are there conflicting details – Do different entries contradict each other?

Research Depth

• Is the tree fully developed or sparse – Does it include detailed information?
• Are notes included – Does the researcher explain conclusions?
• Are there attached documents or images – Supporting evidence available?
• Are multiple generations documented carefully – Or filled with assumptions?

Red Flags

• Lack of sources – No documentation provided.
• Exact dates without evidence – Suspicious precision.
• Large numbers of copied individuals – Possible duplication from other trees.
• Famous ancestors without proof – Unsupported claims.

Research Approach

• Treat online trees as clues, not facts – Use them as starting points.
• Verify each claim independently – Confirm with reliable records.
• Compare with other trees cautiously – Avoid copying errors.
• Build your own conclusions based on evidence – Do not rely solely on others.
