This project is a meeting place for users who share the Q-Y2754 Y-DNA haplogroup, which means they are related along their paternal lines. Users in this group may want to share their family trees with each other to find overlaps and merge duplicate profiles in order to join or expand the World Family Tree and discover new relatives.

According to latest research, as of January 2019 it appears that there are two ancestral Y-DNA lines in haplogroup Q found in the Ashkenazi Jewish population: (1) Q-Y2198; and (2) Q-YP1003.

The Q-Y2198 cluster follows the same pattern as many of the larger Ashkenazi Y-DNA clusters, with (1) a shared direct male ancestor dating back to about the second half of the first millenium CE, as evidenced by initial branching during that time frame; and (2) substantial branching within those subbranches that presumably dates back to the time when the Ashkenazi population began its massive expansion out of a small bottlenecked population, about 700 to 1,000 years ago.

TMRCA (YFull Tree) (as of January 9, 2021)
Q-Y2197: 1,300 ybp (950-1,700 ybp @95%) (Q-Y2197 and Q-Y2198 are at same level)

Q-Y2780: 800 ybp (550-1,100 ybp) (Q-Y2780 is at the same level as Q-Y2754)
Q-YP1004: 750 ybp (350-1,150 ybp)
Q-Y2750: 950 ybp (550-1,450 ybp)

Our haplogroup is a subclade of Q-Y2198.
as of April 2022:

Q-Y2780Y2754/FGC1920 * Y2781/FGC1930 * BZ31/FGC1885+2 SNPs
formed 1250 ybp, TMRCA 900 ybp

Under 2780/2754 we have two subgroups:

Q-A18698 - formed 900 ybp, TMRCA 900 ybp

                 inclluded - Q-BZ37 and Q-BZ3989

Q-FGC1898 - formed 900 ybp, TMRCA 500 ybp

                    included - Q-BZ35 and Q-Y2752

Big picture

We have common male ancestor and 3-4 branches of this family over centuries in Austro-Hungary with the latest (1850-1919) migration to Ukraine/Lithuania and USA.

If you already have BigY results from FTDNA or another SNP testing - it would be great to add you to YFull and look at new age estimation:
