Sorry I can not help you with William since I am just beginning my search. My family is also from Maryland. My grandmother was Florence Ruth Redner. Her parents were William Allan Redner and Virginia Mae Grainger. Her grandparents were William Adam Redner and Florence Hibbard. I remember her telling me once that she was related to a duke and had a sword that belonged to him, but I don't know what his name was and my grandparents are no longer living. They were from Serverna Park in Anne Arundel County.
