A new work on Emilie Todd Helm's visit to Lincoln's White House

[STS Lincolnite]

Did Emile and Mary remain estranged for the rest of Mary's life, then?

I believe they did, but mainly because of Emilie.

They did remain estranged. Emilie wrote a letter to President Lincoln on October 30, 1864 and that is the last known communication between Abraham/Mary and Emilie. It was a scathing letter, from what I can gather, in which she more or less blamed Lincoln for all the misfortunes that she had suffered. She did however see and speak to RTL in March 1865. She kept up a cordial relationship with him until he died in 1926. Yes she outlived him. She died at age 93 in 1930.
