Managing your genealogy research can be exciting, but things often get confusing when you have to merge several family trees into one. Whether your data comes from relatives, online records, or your own research, combining everything correctly is essential to avoid mistakes. If you use tools like Family Tree Maker software, the process becomes much easier — but you still need the right approach.
In this article, you’ll learn simple, practical steps to merge multiple family trees without errors and maintain clean, accurate records.
Why Merging Family Trees Can Be Challenging
When different family members collect information separately, you may find:
- Duplicate individuals
- Conflicting dates or locations
- Missing source citations
- Spelling variations
- Mismatched relationships
These issues can lead to major confusion if not handled carefully. That’s why taking a systematic approach is important before merging anything.
Step-by-Step Guide to Merging Family Trees Safely
1. Start With a Clean Master Tree
Before merging, make sure your main tree is updated and error-free.
Check for:
- Duplicate profiles
- Wrong dates
- Missing parent-child links
- Incorrect spellings
Using Family Tree Maker software can help you quickly identify inconsistencies and fix them before importing new data.
2. Compare Trees Before Merging
Never merge blindly. Review the second tree carefully and look for:
- Repeat entries
- Contradicting records
- Unverified people
- Unusual relationship links
If the contributor has notes or sources, read them to understand their research.
3. Match Profiles Manually
Automated matching tools are helpful, but manual review is essential for accuracy.
Check people with:
- Similar names
- Close birth dates
- Matching locations
Confirm they are truly the same person, not just a coincidence.
4. Keep Only Verified Information
If you find conflicting data — such as two different birth dates — keep the one supported by evidence.
Reliable sources include:
- Census records
- Birth or death certificates
- Church records
- Military documents
Always prioritize traceable proof over assumptions.
5. Use Merge Tools Carefully
Most genealogy tools, especially Family Tree Maker software, offer built-in merge features.
When using them:
- Review every suggested match
- Confirm relationships manually
- Reject questionable matches
- Save backup copies before merging
Create a separate backup file of your main tree so you can restore it anytime if something goes wrong.
6. Add Sources While Merging
Every piece of new information should include a citation.
Sources make your family tree:
- Trustworthy
- Easier to verify
- More valuable for future generations
Avoid adding unverified or unsupported facts.
7. Check for Duplicates After Merging
Even after merging, duplicates may still appear.
Do a final cleanup:
- Remove repeated profiles
- Correct spellings
- Recheck family relationships
- Reorganize media files
This ensures your tree stays neat and reliable.
Tips to Avoid Errors When Combining Trees
- Merge trees one at a time
- Keep separate notes for each contributor
- Never delete information without confirming
- Communicate with family members for clarification
- Update your tree regularly
- Backup your files before every major change
