I'm looking at naturalization paperwork for George SAWCZYSZYN, and the Certificate of Arrival (Form 145) within the packet has the name Jan BURYAK. The names aren't even close, so I can't figure this out. (If someone were going to change their name from BURYAK after arriving, I doubt they'd choose SAWCZYSZYN! :) The ship and arrival date on Jan BURYAK's Form 145 match what George states on his paperwork though.
Further confusing me, I can't find George SAWCZYSZYN on the manifest he should appear on. According to his naturalization papers, he arrived at New York from Bremen, Germany on the ship Neckar on 2 Feb 1910. I've searched the manifest for this vessel and can't find any SAWCZYSZYN, let alone a George SAWCZYSZYN.
This isn't the first time I've come across someone whose naturalization papers give a ship name/arrival date and I can't find them on the manifest, or the ship and arrival dates don't match (off by over a month).
How strict were immigration officials about the accuracy of this info? Could an immigrant without a Form 145 just give an approximate date of arrival and the Bureau of Naturalization would find the closest arrival and use someone else's Form 145?
Thanks for reading!
