It did say it was a Jessop, although I wasn’t sure that told us which Jessop because I’ve been led to believe that a good number of people at the site share a few last names.
Even the men sometimes change their last names. I was reading an ex-FLDS message board the other day which mentioned a guy named William Timpson/William _____ (one of the common last names, can’t recall which) being one of the senior leaders at YFZ. It was clear he was originally William Timpson, but had apparently changed his name as he rose up in the organization.
