Patty, I tried e-mailing you but it bounced back.
I am a descendant of John Alexander and Mary too. My connection is as follows:
John and Mary's son Joseph
Joseph and Susannah Monger's son William
William and Angeline Pilon's son Peter
Peter and Elizabeth Arquette's song Norman
Norman married Catherine Millar. They had two sons and a daughter. One son (Gary) is deceased.
The daughter is my grandmother. She had 2 sons and 2 daughters, all are living. The youngest daughter (and youngest overall) is my mother.
