I have looked into the Canadian Census of 1871, 1881, 1891, 1901 and 1911. I find this couple (Regis and Arzelie) in the census of 1881 and 1891, but not in those of 1871 or 1911. This could mean that they were in the US before 1881 and after 1891. Regardless, the census of 1881 and 1891 gives their 6 children: Rose Anna, Andre, Wilfrid, Marie Louise, Regis and Arzelie. With everything that I have read from others it would appear that they married in the US, returned to Canada to start their family, and returned to the US after 1891. However, several of their children married in Canada and likely returned to the US afterwards. The exception is Andre, who married Emma Beaupre and remained in Canada at least until 1921 (Canadian Census).
