I'm looking for immigration records, such as the ship he came over on passenger list, for Alexander John Stemporzewski. I already have his naturalization papers and his certificate of arrival, so I can tell you that came to the Port of New York on June 10th, 1913, under the name "Alexander Stempozicki from Rotterdam, Holland onboard the SS Noordam when he was 16 years old. He was born on July 10th, 1897 in either Koszedary, Lithuania, or somewhere in Poland. After leaving New York City, he lived in Lowell, MA for the rest of his life. It's likely that he immigrated with his brother Peter, who's birth year I don't know.
Last person on these pages. He was headed to Peter in Massachusetts, so Peter was already in the US.
He is second from the bottom of this list.
