Hello, Lyn! Don't know if you've tried Griffith's Valuation yet or not. I believe there was a Valuatation in 1850. I sent info to the list a couple weeks back about free Griffith's lookups. If you'd like it, email me and I'll send it to you directly as I so recently sent it to the list. Don't know if this is of any help, but hope so! Happy hunting!! Amy
