Frequently Asked Questions
ISOGG pages: Y-DNA Project Help
Can you find surnames associated with my Y-STR haplotype? Can you search for matches of my Y-STR haplotype?
If you have a FamilyTreeDNA Y-DNA kit join J2-M172@FTDNA and we will group you with kits that are nearest to you (usually Y-STR37 or 67 needed).
Our focus is haplogroup research which can help to connect to the Y-history in the last 1,000 years. We are volunteers and cannot carry out research on relations in individual family lineages (genealogical time, private haplogroups) in this large project which includes the entire J2 haplogroup and over 2,500 members. You can try to ask for Y-STR haplotype help in the J2 Facebook group.
If you have no FamilyTreeDNA Y-DNA kit or no matches with your FTDNA kit you may research yourself in the Y-STR databases with your haplotype to find associated surnames and origins: ysearch.org, smgf.org, yhrd.org
My results shows me as J2a4 [example]. Why is my haplogroup name not used here and in the project group name?
Haplogroup names are very volatile as the tree gets refined constantly. Always use the terminal SNP you have been tested for, in the example here the historical name at FTDNA completely would be J2a4-L26. You can find name versions for the following test providers: FTDNA, Genographic Project, 23andMe
I have 12 (or 25) STR-markers. My kit was not grouped and I do not have matches. Why?
Only a rough grouping may be possible without detailled Haplogroup/SNP test. STR-Marker upgrade and/or Deep SNP testing (FGC Y-Elite, FTDNA BigY, J2 SNP Panels, chip tests like Geno 2.0 or Chromo 2.0) is suggested to find distant matches.
I have 37 (or 67) STR-markers. What can you tell me?
Depending on your haplotype and SNP tests a basic to good clustering may be possible. Advanced SNP test is suggested.
Why do you always suggest to do (advanced) SNP Tests?
Advanced SNP Tests are needed to refine (or certify) deep clades and to confirm matches not clearly in one haplogroup (overlapping haplotypes).
Looking at the Y-DNA Classic Chart I can’t find my result?
