Understanding DNA Matches on FamilySearch

DNA Matches Explained

FamilySearch connects with DNA testing companies to help you find genetic relatives. Here's how to use this feature:

Step 1: Link Your DNA Test

Go to Activities > DNA. Follow the prompts to connect your test from Ancestry, 23andMe, or other providers.

Step 2: View Your Matches

Once connected, you'll see a list of people who share DNA with you. Matches are sorted by the amount of shared DNA.

Understanding Centimorgans (cM)

• 1400+ cM - Parent, child, or sibling
• 600-1400 cM - Grandparent, aunt/uncle, half-sibling
• 200-600 cM - First cousin, great-grandparent
• 50-200 cM - Second cousin, great-great-grandparent
• Under 50 cM - More distant relatives

What to Do with Matches

• Compare family trees to find the common ancestor
• Reach out to matches who have uploaded trees
• Use DNA to confirm or break through brick walls
