Here are a few more tips:
- Ancestry DNA now gives you the number of centimorgans (cMs) in the largest segment you share with a DNA match. Unfortunately, it does not appear right in your list of matches, but you'll see it when you click on the person's name. I've been entering the info on the largest segment in the "notes" field for each person right on the list of DNA matches. Focus on individuals for whom the largest segment is >20... or even better, >30 cM.
- One disadvantage of Ancestry DNA is that they don't show you the number of cM for each segment like MyHeritage and FTDNA do. Upload your Ancestry DNA to those sites to find more DNA matches; in the process, you'll be able to "fish in all ponds" and find more matches. It's worth it to pay the one-time fee of $20-$30 to access DNA tools on MyHeritage and FTDNA, like a Chromosome Browser.
- Join the Facebook group Jewish DNA for Genetic Genealogy and Family Research. You'll learn a lot there. Be sure to check out the files section!
