Nathan POBERESKY was a relative (prob. bro) to my Israel (SRul) POBERESKY. Nathan and his wife Bessie and 10-11 kids all ended up in NY. One child (prob. his oldest) was Mary (1878-1969) who married Philip SELDES in teh Ukraine. They ended up in Brooklyn. Any descendants of their kids out there? (Joseph and Anna Seldes, 1899-1961; David SELDES 1903-74; Clara/Clair SELDES c. 1906-?; Abraham SELDES 1907-88).
Love to exchange more info (I have LOTS on Mary's parents and siblings and cousins).
