The commenter never wrote back I think.
I just got this comment… about that article
This will have to be investigated thoroughly. As you say it has a great bearing on our family tree and leaves us in limbo as to whom we are actually descendants of.
The author of “Les Quesnel”, Albert Aimé Quesnel, was a respected genealogist who took great pride in his work and in the Quesnel name.
He does admit that errors in his research will be found and hopefully rectified.
Please send me your email address and I will send you more information about this proud member of the Quesnel family.
By the way, my mother was born Isabella Lagacy.
My best regards.
Jean (John) Aime Quesnel
