I've not seen these photos before. I didn't think about Mary Todd. Duh.
Todd was born in
Lexington, Kentucky to John and Elizabeth (Smith) Todd, and moved with his parents to
Illinois in 1827. His first cousin was
Mary Todd Lincoln, wife of
Abraham Lincoln. Thus he was cousin-in-law with the President.
[1] Another cousin-in-law was
Confederate General
Benjamin Hardin Helm. Helm's father was Kentucky Governor
John Helm; Helm's mother was a first cousin, three times removed of Colonel
John Hardin, who was related to three Kentucky Congressmen. wikipedia
