I would like any information to trace back beginning with William McKinley Yaw (1896-1981) He lived most of his life in Iowa and fathered aprox 18 children. In asking around, no one remembers the name of his mother/father or where he was born. I was told he had a PA connection. I believe brothers and sisters of William were Henry, Frank, Laura and possibly Grace. I have a lot to offer from the Iowa connection, but nothing previous. Any help will be greatly appreciated.
