Robert Todd Lincoln --The vitals

[Gene C]

From what I understand, Mary and Mathilda were good friends. She probably knew Mathilda and Abraham well enough to know that a romantic relationship between the two was not going to happen.

Regarding Mary & Abraham, in his letter to Mary Owens, he mentioned he did not have the financial means to provide some of the nicer material things in life and she would probably be disappointed if she married him. I'm sure he felt the same about that with Mary Todd, especially with her background and education. She had her share of gentleman callers too. One big attribute to her credit, she was able to look beyond his physical appearance and background to see his true character, when many others didn't.

I think Lincoln was infatuated with Mercy, but in love with Mary.
