Rabbi David Segal (the TaZ) - Tracing My Lineage to the Taz

Dear Dr. Schmukler,
I am compiling an index of Rabbinical yDNA haplogroups (https://www.geni.com/projects/Rabbinical-Lineages-yDNA-and-Haplogro...) and due to you expertise on the TaZ lineage I would like to ask whether you can point me in the direction of any patriline descendant of the TaZ who is on GENI (or otherwise) who has done yDNA testing and can be the source of the TaZ haplogroup to add to the index. This little piece of information can be enormously useful to myriad researchers in certain situations. Any feedback on this request is highly appreciated.
Cordially,
Adam Cherson
MPA-JD

Another defendant here. Who were the relatives preceding The Taz? Does anyone have the names of his grandparents, by chance?

My great grandfather was a direct descendant of the Taz ,Ben Acher Ben , son of son
