Immediately following their marriage, and in defiance of the custom of the time, Gaboury travelled to the west with her new husband. They went first to the area near the confluence of the Assiniboine and Red Rivers near what would later become the Red River Colony and eventually modern Winnipeg, Manitoba. They wintered at a Métis encampment near Pembina (under British sovereignty at the time but now in North Dakota), where the first of her eight children was born on 6 January 1807.
