Jean, there is so much misinformation on James, that I cannot possibly come up with anything definitive to tell you. Some have him married to Mary Nall.I just don't know about him.There are too many conflicting "stories" about him out there and nothing that's proven. I had "James" in my ancestry...one is son of William Younger and Mary Watkins;one is son of Thomas (I think this is your James),one is son of Williamson/Mary Bomar Younger, and one is son of William/Louisa Patton Younger.
Sorry I couldn't help you. It's all very confusing.
