I am Catherine Sterling (Stirling) Smith. My great grandfather was Jessie Price Dorman. His oldest daughter Mary Estelle Dorman Sterling was my grandmother who died when my Dad, Emerson Lincoln Sterling was 18. He was very close to his mother and was told by her that her father was adopted. He was Indian. The only thing I have found so far is that he was from Kansas. If you have found any info since this was posted please let me know.
