No, I am not related...just wanted to help.
Was she married prior? Tried to find another marriage certificate in same church but maybe didn't look hard enough. Since she carried the
Robertson name I wasn't sure.
And you are correct...it is half the fun trying to always unlock one more generation.
Did you have her father and mother by any chance? Notice that there was a child under the
Lavallee name that died in
Sherbrooke and her father, who was deceased at the time was a Peter Lavallee...and he appeared to have a brother named Thomas who was the witness. Wondered if that could be the Peter and Thomas in the other records you to which you were referring. Probably not, but worth mentioning just in case.
You have a wonderful weekend!
