Thanks Angela! That really helped. I didn't even know about those other children. I do know that Georgiana and Urgele had another son named Edmund. My mother has his birth registration because he was her grandfather. I've also heard that there was another child named Ellis who died very young.
Do you know of any Metis or Algonquin connection with Urgele Pigeau? My mother has seen some references to him being an Indian Chief at Golden Lake near Pembroke and we'd like to confirm it if possible.
