David,
I am Diana, not Rachel, as stated before. I am leaning towards William Alpert being the s/o Simon and Rosa, because William's daughter married a Levine, and granddaughter states that she is related to Feinberg of Dannemora. The 1900 census for that town shows Simon, Rosa, Lena Levine, dau., etc., plus states that Simon came to the USA in 1889. Wife, Rosa, came in 1890, Dau., Lena and Granddau., Fannie, etc. came in 1890. WILLIAM ALPERT CAME IN 1890 AND WAS NATURALIZED IN CLINTON COUNTY. HE IS UNDOUBTEDLY A COUSIN OF MAX AND LOUIS, SINCE HE ENDED UP IN BURLINTON, VT, AS DID MAX A ND LOUIS. It would be easy to prove with a death cert. for William Alpert, if there was someone in VT who could obtain it. I am in MI, and am interested in this because there are two inter-marriages between Steinberg and Arcofsky in Russia (sister of William Alpert's wife, Rachel Arcofsky) and because the William Alpert descendants are related to me through a daughter's marriage. Therefore, I want to identify positively William's parentage. Plus, I have contact with all William Alpert descendants, grandchildren in their 80's. If you are looking for all descendants of Jacob and Ida, then these people are your family, as well.
