(He's my 7th great grandfather.:)
Hatte, geni finds a path from him to you, you think there's an shorter one? https://www.geni.com/path/Rabbi-Menachem-Twersky-1st-Chernobyler+is...
Dimitri Vulis -- I don't know. I doubt it's a close relationship, because my Reib - Rubenstein kits are 5th to remote cousins to the Twersky descendants on FTDNA. We seem to share some segments with Wertheimer and Twersky. Probably a more distant shared ancestor and just coincidentally my gg grandfather appears to have been a follower, based on the given names and geography. I know they were religious because my great grandfather and his cousin's house established the first synagogue in Muscatine, Iowa in their basement.
amazing stuff! Maybe Private User / Jeffrey Briskman (I can't find the paper cited above, but another related one is https://www.academia.edu/26048275/The_Y-DNA_Genetic_Signature_and_E... ) can offer some insight on Twersky DNA. (I heard Briskman's done some amazing work on Vulis DNA, have yet to find the time to read it.)
I have found the document mentioned in the first message at this URL: https://hcommons.org/docs/the-worldwide-twersky-surname-study/?bp-a...
