We have two different John S. Lindleys here. John Sanford Lindley, the brother of Agustus, was the son of James M. & Sarah (Felts) Lindley. He married Alice Moore who died in a state institution in S. Dakota. Anyway, he was a doctor and worked for the Dept. of the Interior in Indian Territory. I have more info on this if your interested. I had a mishap with my data and can't put my hands on his birthdate at the moment.
John S. Lindley b. about 1838 married Muskoge (spelling?) and was the father of William Walter, Annie E., James Wesley, M. Georgia and John M.. He later married Eliza Stuart. I don't have info as to who his father was but I believe his father may be a brother of James M. Lindley, John Sanford Lindley's father.
It gets confusing because there are so many family members with the same name. I'll be glad to share info and would appreciate any help in figuring it all out. I just need to do some re-input, ugh. Hope this helps--
