A copy of the letter would be a great ideal. Is it written in English or French? Send me a copy, I'll see what I can make out of it.
You seems to be very interested in your family genealogy. Guess what I will send you more stuff this weekend. It's getting late, I just finish get my new computer running with all my Genealogy data. If you are in Wisconsin that make me 1 hours ahead of you and it is passed my bedtime.
