I'm very familiar with Tudor Hall in Bel Air and stayed there several times when it was owned by Dorothy and Howard Fox. It was through my membership in P.A.T.H. (Preservation Association for Tudor Hall) that I met Mike Kauffman and others experts on the Booths and the assassination. Every two years they would hold a symposium which would include guest speakers, as well as visits to the various sites associated with the Booths. I'm sitting here looking at a framed poster I was given by the Foxes depicting JWB, Junius, Edwin, Tudor Hall, etc. It was specifically designed and made for P.A.T.H. Howard and Dot died within a few months of each other and never left a will as to what they wanted to do with the home. It was later sold at auction and bought by a couple who obviously didn't keep it very long. I've been a member of the Surratt Society for years and get their monthly newsletter, and heard about the sale of the home to the historical society. I also subscribe to a publication (from Clinton, Md.) of The Lincoln Assassination Journal. I'm sure you are aware that there is another home not far from Tudor Hall that has part of the original Booth log cabin in its framework. I can't remember exactly where it is, but I recall visiting it during one of the symposium weekends and taking photos of it.
I believe the “old log cabin” structure is the house this sits at the intersection of Prospect Mill Rd & Churchville Rd. I read an article in the Harford Liberal Rag (Aegis)that they believe the log cabin has been built around numerous times and now appears as a white, 2-story dwelling.
