I was never able to confirm which passenger list, ship, or date/year that my great-grandfather came over on. According to his naturalization records, he came over on the Tartar Prince in 1899 but the Ellis Island site or here does not have any passenger manifests that sync up to the date on his naturalization records. I am thinking either on is off my a few months or a year or two, or the other (given that both sets are about a hundred years old by this time). I have passenger lists confirmation and naturalization records on all great grand parents except for this one. Also, he is coming from the Old World (Italy), so I am not a hundred percent sure which port he actually departed (even if it is cited).
PS Can't find any old world records.
