Mike Vayser--this is very helpful, and you have uncovered a completely new relative's name in your reply! I have not seen the 1900 marriage of Fanya Meshmar to Gershka Abrashkov, and need to find this data. It does not come up in my searches on jewishgen.org. Can you please direct me to your source? Yes, the other couple (Moysey to Dobrysh) are my paternal grandparents. I am so excited to learn of a new aunt & uncle!  Thank you.
