I am looking for the three half brothers and sisters for my father. His name is Arthur Pettit born in Palmerton-Lehigh, Pennsylvannia. "John Paulus" and Elizabeth Pettit, daughter of Newton Pettit Sr., had a son out of wedlock on January 18, 1943 who is my father Arthur Pettit. He would like to get in touch with his half brothers and sisters if possible. I hope you can help me.
