Did Vinnie Ream visit the White House daily for 5 months?

If the visits did take place then I think Mary Lincoln never knew about them. This link includes a letter Mary wrote to Vinnie.

H. Donald Winkler writes, "Ward Hill Lamon, the U.S. Marshall for Washington, arranged a new passage for Lincoln to enter his office unseen. It helped to ensure his safety. It was also used by Ream, and it kept the sittings secret from Mary."
