Geneanet DNA: Three years already!

Geneanet DNA celebrates its three year anniversary this month! There have been a number of updates to the tools since it was launched — have you tried the Chromosome Browser, noted your haplogroup, or used the new Annotation feature?

On February 17, 2020 — just as the world was learning about the Covid-19 pandemic — we launched our free Geneanet DNA service. No “saliva kit” was offered for sale, due to the very restrictive legal environment in France regarding “recreational” DNA testing (i.e., not ordered by a doctor for medical reasons, or a court for paternity reasons). Instead, we told our members that if you have tested with Ancestry.com, 23and Me, MyHeritage, FamilyTreeDNA, or LivingDNA, you could upload your DNA computer file to Geneanet with the hope of finding matches to European cousins. The response was enthusiastic!

Link your DNA to yourself in your tree and let Geneanet find a common ancestor with a DNA match to a cousin’s tree!

Rich features in our free tools

As we enter the fourth year of Geneanet DNA, we are excited about how our database has grown, but even more excited to see how you are using our tools to find long-lost or previously unknown cousins. We have upgraded and expanded our service every year:

  • Haplogroups: reliable paternal haplogroup results for Ancestry, 23andMe, and MyHeritage results, and maternal haplogroup results from 23andMe, for tests since 2019; some older kits will also work. Read about haplogroups here
  • Cousin matching through trees: the shortcut to identifying the common ancestor! Import a GEDCOM file of your tree and don’t forget to link your DNA to to your tree! (Premium feature)
  • Chromosome browser: see on which chromosome and segment you match with cousins, to help identify your common ancestor; learn more here
  • Shared cousins: See which cousins you have in common with a match; very useful if you have already identified a common ancestor with one of the matched cousins
  • Accuracy indicators: Green, amber, or red… Green is best!
  • E-mail notifications: More fine-tuned control over messages (no need to be told about tiny 10 cM matches)
  • Improved sort and filter options: sort by Degree of relationship, Match date, Accuracy, Number of segments, Longest segment; filter by Family tree available, Common ancestors found, High and/or Medium accuracy, total cM, minimum segment size in cM, minimum SNP size
  • Search matches: by family name, first name, nickname, or Geneanet username
  • Results list: readability was improved and the number of shared segments and the size of the longest segment were added to save you time
  • Matches detailed data export: import your data to DNA Painter or other tools
  • Annotations: our most recent feature lets you record private notes for each match, and you can edit, search, and filter for them. This was a feature often requested by members!
Our improved results list introduced last summer helps you zoom in on interesting DNA matches.
If you and your match both have trees at Geneanet, the names in common will be listed!

So… who should you test with?

Our tools are designed to work with all five of the major DNA testing providers. Be aware however that there is an advantage with testing with the biggest DNA kit database, Ancestry DNA: you are more likely to have matches there, and after importing your DNA to Geneanet you will have more European matches. Also, neither Ancestry nor 23andMe allow DNA uploads from elsewhere at this time, so it’s best to start with one of these two. Our haplogroup calculations are reliable for the three largest providers for all DNA kits done since 2019, and a number of older ones as well. The prices of DNA kits have dropped considerably these past few years — if your kit is more than 5 years old, consider getting a more recent kit done!

Our chromosome browser shows you exactly where you match with a cousin: both of you inherited this segment of DNA from a common ancestor. In this case, there is a match on only one chromosome, but it is fairly long at 42.43 cM, indicating a common ancestor recent enough to be in the genealogical period, when records will be available.

Find Help

DNA is a complicated topic. No worries! We have a number of help pages available, including specific pages for each of the major DNA kit providers. The Genetic Genealogy section of our forums is a place where you can ask questions and get responses from other members. The forums are monitored by support too. And as always, if you are a Premium member, you can open a support ticket directly. Concerns about how DNA is stored and used at Geneanet? Read our DNA Code of Ethics and our help page, Understanding and configuring privacy settings at Geneanet. Finally, for in-depth information about DNA testing for cousin matching, visit the International Society of Genetic Genealogy website.

We wish you good luck in finding long-lost or previously unknown cousins!
