Grant and Lincoln's invitation

[L Verge]

I have never read the book by Dr. Wayne Temple on Lincoln's Travels on the River Queen, but perhaps some of these questions are answered in it?

While googling, I found an interesting painting done after the Hampton Roads Peace Conference, along with some history of the ship. I was amazed to find that it was bought in 1893 by the Mount Vernon and Marshall Hall Corporation that ran excursion trips down the Potomac River with stops at Washington's home and also a wonderful amusement park on the grounds of the old Marshall estate in Maryland. I wonder if my grandparents were ever on board the ship because it made the runs until the early-1900s.

I remember those Potomac River cruises that were still going on when I was a child and teenager. I took several trips on them, including their midnight cruises to the amusement park. In those days (1955-60), they were run by the Wilson Line.
