after talking with family members we have decided to put this out there. My great grand father Joseph Knapp b. 1852 in Indiana was m to Margaret Dewald in 1876. To there marriage we have 13 children including my grandpa Jacob.
We are searching for others who might have Joseph as their father. Been told that he had several affairs resulting in more siblings. Would love to make contact with them.
Joseph was m in Fairbault Minnesota and lived in South Dakota till his passing in 1929.
