We sold our 40' sailboat this week, after many years of adventures around the coast, and thinking about boating reminded me...
My maternal grandmother Mavor had tucked among her family photos this 1904 newspaper clipping of the Grand Trunk Boating Club. I don't know if my grandfather or his brother are in this photo, or in fact members of the club. I have gone through many newspaper articles of Regattas involving the GTBC and have not come across the name Mavor, and have not found any members list. But there must be a reason she kept it, I know they both loved the water.
My paternal grandparents went canoeing at the Maple Grove Boating Club, near Chateauguay, Quebec.
Looking around, searching for information, I came across some yacht club and boating club publications, with lists of members.
Perhaps your ancestor belonged to a boating club.
