Thanks for the reply. I know my Ostrowski ancestors were part of the Sweetest Heart of Mary church in Detroit, and their records are in a library there. I've had someone look through the records, but they only say Poland on them :( I was able to get the maiden name of Julia and the parents of Vincent and Julia's father's names in this way. However, still no village.

I've had to go to more fuzzy methods like a surname project because I feel I've exhausted all the direct records relating to my family. If I can find that the Vincent Ostrowski family group was linked with another family group, there is a good chance that they were siblings or cousins. I could then use that other family group to find a village which may be easier, then I can order records from that village to prove if my family group is really there. Or, nowadays, I can try to use DNA testing to see if I'm closely related to another family descendant.
