Can you help me find the parents of Frank Prettyman of Philadelphia who was born 1 May 1895. Based on the 1920 US Federal Census, he and his mother were born in Pensylvania and his father was born in Delaware. I don't know there exact names. There are so many Prettymans in Delaware and a few named Frank. But I'm unable to tie them together. The Frank Prettyman of Philadelphia was likely white or mulatto. Any info is appreciated.
