I'm curious on who sent you the note, and why.
A suggestion would be to contact the local county historical society +Devon Noel Lee
. It's not uncommon for things people feel are of historical interest to be willed to the local society. I've found them to be the best place to start.
Another suggestion would be looking for an obituary for Betty Kinnaird George, see if it lists children or heirs. Contacting one of her descendants might prove fruitful. Don't be surprised though if you don't get an answer. Many people are wary these days of queries from people they don't know.
Lastly I would suggest contacting the county probate court, to find out who handled the estate. There should be an inventory and some kind of disbursement record (who got what) whether there was a will or not. The name of the lawyer or executor/executrix should be on record, you could contact them.
My experience has been having the most luck with historical societies or the courts. Happy hunting!
