Please see other message I posted today, 11/7, on the movie "Lost River" on the life of Anna Ella Carroll, Lincoln's political/legal advisor and military secret agent. She was the daughter of Gov. Thomas King Carroll, of the Henry James, Susquehanna Pt. line. You are correct, AEC was raised in her father's N. Ireland Presbyterian tradition.
If you still live in Maryland please try to attend the movie premier.
