I'm still puzzled that Matrona's naturalization intent and petition only says Minsk and not the precise location that shows up on her arrival manifest. How did the office clerk cross reference the EI manifest with her application for naturalization. We sort of can not go further until you find Matrona's precise place of birth. Possible that all 3 of them, her 2 husbands were from same vicinity aka gubernia Minsk. Birds of a feather fly together.
