I am researching Koceja relations in Wisconsin. I found a marriage between Valentine Koceja and Anna Woida in Peshtigo Harbor in 1873. This family moved to Town of Liberty in Outagamie County around the late 19th century. Some of their children moved to Illinois.
My connection is the sister of Anna Woida. She was Mary Woida Dura who immigrated in 1881 and moved up to Peshtigo Harbor with her husband and children. When they came to America there was a Paul Koceja on the ship. I think that he was Valentine's father.
