How Ya Doin'?
I have gggranddad as David Bertrand, father to Zotique b.1848/49. David's marriages as:
1st to ??????
2nd to Ann McKay Sept 3, 1867
3rd to Margaret/Marguerite Simmons
I ask about the first marriage because of the ages of Zotique and some of his siblings, all somewhat verified. And David was repeated in the line.
And of course, is your David my David or a sibling/cousin?
