You' re welcome.
So neither of these 2 check into your family tree.
Rzucek, Franciszek Trzebowisko 30 1872 1902
R...rzek, Franz Godowa 50 1850 1900 view Ellis Island
You mentioned that you have Frantiszek's brother's arrival manifest. If that brother's place of birth is Godowa or Trzebowisko than I would think that is the place that Frank was born in. You did say that you have not located your ancestor's arrival manifest. Any other US documents like a draft registration form, naturalization intent & petition? I'm sure you searched the children's baptismal record for parents place of birth,

The largest concentration of RZUCEKs is around Rzeszow and both locations, Godowa and Trzebowisko are around that location. Since the ancestor's married the year the female ancestor arrived to America than I suspect that their families were from within 10 miles radius or same location.
