Those are all facts that we do have documentation on except his birth certificate. And as you noticed that Leon Curl and Lavada Smith married 1925. Dorman was born in 1923. Everytime my family would go back east for a visit, it was like that hole town knew our family secret but to this day won't speak up. Even after they all have been gone for quite sometime now. His birth certificate and their marriage license have been nowhere to be found conveniently. I have found nothing in Colorado. It is believed in a small way that Lavada Smith got pregnant at the age of 14 or 15 from a (political figure) in that town. And Leon Curl stepped up to the plate so to speak. She might have gone to Colorado to give birth. It was just a family myth I thought would be a good place to start.
Also, it is possible that one of Lavada's sisters is Dorman's mother and Lavada took him in. I don't know.
