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 https://www.yfull.com/tree/Q-Y2780/
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:
