Catharina Ostermann marries in Bochum 1698 Hendrik Kruseman from Hamm, born 01-05-1671, died 25-01-1727 Hamm. Her birth and death, I do not have. According to Ned. Patriciaat [geslechtsbuch] she was a daughter of the Rev. Heinrich Ostermann. I am looking for Catharina and her ancestors. I am told that she might be related to Graf Ostermann (Russia).
It is a well-known family from Bochum, I've heard that there are ortsippebucher, this consists of this family in Bochum? Or is there anyone who can help me further?
