I've attached my father's birth certificate which shows his father was born in Enis, TX. I haven't found record of an Enis, TX I'm guessing that he told them his was born in Ennis which is in Ellis County.
DC House Sr. was born 20 Feb 1898. perhaps in Ellis County.
I have no conclusive evidence and lots to the contrary. His WWI draft card says he is from Camden, AR. His WWII draft card say Oak Cliff, TX.
I'd be happy to hear if you have any information.
