of all those kids, only two had children: Ernest had a daughter who has since passed away, (no children of her own). The other was Helen Mary, who had twins, my Mother, Gale and her brother Arthur. Gale had 12 children - I am number seven of them - and Uncle Arthur had 6 kids. Unless your relative is a brother or perhaps a cousin? to my great grandfather William Levack, then this line didn't go very far.
so glad you found someone who knows some information!!
