Hello to everyone! My great grandfather is Delbert Wright. I have been told by many family members that Delbert's father Jim Wright is really his stepfather. I was told that his biological father was an abston. They said his mother was pregnant when she married Jim Wright and so gave the baby the Wright name.I believe Delbert's mothers name is Maude Elizabeth Miller.I have no idea how to trace this type of information. I would love to hear from anyone who has any information.
