Reward: $200 for a family document from Poland verifying their location prior to emigrating.

Krzewinski Family
First Name(s): Joseph, Frances nee Kochanny, Bernard, Leon, Elizabeth, Helena, John, Leokadya, Frances M.
Married Name: Krzewinski
Maiden Name: Frances was Kochanny (or similar spelling)
US Location: Bay City, Michigan (St. Stanislaus church)

Overview: Joseph and Frances Krzewinski came to the USA about 1885. Family said Joseph was an overseer on a farm owned by a Germany family. Joseph was a Prussian soldier and received the bronze cross for participating in the Battle of Koniggratz.
The strongest information I have is from Bernard's daughter who said her father was from Grudziadz. Also, Frances Kochanny's (Joseph's wife Frances) cemetery record says she was born in Zachud or Zasbod?
I want to find a record from Poland (e.g. parish record, civil record) that verifies that Joseph, Bernard and family came from a certain town or village.

Key Documents:
What I've done: I've ordered the Grudziadz baptism indices from the LDS films and am waiting for them to arrive to check whether they were truly from the town of Grudziadz itself.


Tips: I think finding the Krzewinski passenger list would be productive, but I have been able to find that anywhere yet.
