Very good, Roger, it's Eliza Caldwell Browning. They boarded together in Vandalia in 1836. A. Lincoln had known her husband from the Black Hawk War. And Orville Browning indeed became a cabinet member in Johnson's cabinet, he succeeded James Harlan.
Lacking the lots of (19th century slang) "coach wheels" you win my best wishes for a wonderful weekend (especially for all the good things money can't buy).
