Genealogy / Dawidowski, Kuper - Locating Ancestors [4]

Hi!
I'm trying to locate my poland ancestors. The information I have is that they were from Gowidilno. I found some information looking under the Sierakowice parish.

Adam Dawidowski and Eva Kuper married in 1845. I haven't been able to find when they were born or who their parents or if they had any siblings.

They had 5 children, I also found their babtism records searching under Sierakowice parish.
Eva Ludwika born 1848
Jozeph Ignaz 1850
Marianna Franciska 1853
Josephine marianna 1858
Michael (miachael) August 1859

I only know the information of Michael Dawidowski after that because he was my great great grandfather. He married Augusta Anna labuda in 1885. His father Adam was deceased at the time. I don't know when he died.

They had 3 children in poland
Leo
Eva who died
anna
They came to America in 1892 and settled in Wisconsin. I found all the information after that since they came to Wisconsin.

I don't know if any of Michaels other siblings got married, if they had any children or if they even came to america.

Augusta Labudas family is that I know that she at least had two brothers Joseph and Johann Labuda. I have the death certificate from Johann labuda he died in 1886 and I found out that his wife at the time was Josephine. I don't know who they married or if they had any children.

Her dad was deceased at the time a Stanley labuda. Her mother Franciska got remarried to a Franz Hoppa. I know they had a child in 1885 named Martha. I don't know if they had any children before Martha since I don't know exactly when Stanley died and when she got remarried. I know they came to America because I found extra siblings looking in wisconsin records.

I would appreicate any information anybody could give me or of any useful websites to search for information.

Thanks,
Janice
