I have not checked the CULHAM Genforum for a while, so apologies for my tardy response. In the year 2000, we did alot of work on the CULHAM family as a millenium project, and a large gathering of the family was held during the summer of that year.
The 1933 chart you have is sadly out of date and we made some exciting discoveries in 2000 - one of them being that Thomas CULHAM was NOT married to Ann Evans.
I would love to get in touch - our information on your branch is sparse.Please contact me by email.
