Bernard Shapiro was definitely Naturalized. I should have, but I haven't ordered his record yet. I'm more concerned with the Pallack-Gutofsky side at the moment, because my grandfather's cousin is working on the Shapiro line. The census reports say all the others were, excluding perhaps Minnie, but I haven't been able to track down any of those records. I put in a request for a search with NARA's Great Lakes Region twice and for some reason they still haven't gotten back to me months later. I actually visited and looked at the soundex microfilm index by hand and that didn't warrant anything. No passport applications on Ancestry show up. Can't imagine they were Naturalized anywhere else but the Chicago area.
Haven't had any luck with Ellis Island or Castle Rock, etc. Even using the One-Step soundex search....
Samuel Pallack always said he was born in St. Petersburg and that's what is on most of the records, except for his WWI Draft Registration Card which says Krimach. I assume from JewishGen that it could be Krynki, Poland. Minnie was born in Grodno, Russia (Belarus, I'm guessing) on her death certificate. Bernard was born in Mogilev, Belarus and Ida (nee Schwartz) may have been born in either Iaşi, Romania or Beltsy, Romania. Samuel Shapiro's father, Zalman Samuel Shapiro, was born in Lithuania and died in Mogilev.
My grandfather really doesn't care about his Jewish roots (in fact, he wouldn't admit to being even ethnically Jewish for the longest time), so I know very little--really appreciate your time and knowledge.
