I have dabbled with a family that resembles this line - as per a private message you sent to me on Ancestry.com. I thought we should post again here in case Pierre knows something to tie the family. I spoke to Pierre about my Esperance aka Maria Ducharme who may have used Morse. Our Maria had a sister Louise(a) apparently but I was told by Pierre that she mrried someone with a different last name than Letendre.
I will look in my records but I don't have much more than what Pierre gave me. I have been working on my side as well as other things.
