I found the marriage announcement below for the subject people (g-g-aunt and uncle) and could not find out who or what church the minister, Rev. S. E. Colwill, was affiliated with. I looked in the history books Qu'Appelle - Footprints to Progress, and Indian Head, History of Indian Head and District, but did not find any mention of Rev. Colwill.
The 1891 census record for Northwest Territories; Assiniboia East; Qu'Appelle shows William Smith and Jane Ann Smith as Methodist, and C of E. (Anglican), respectively.
This is a long shot but has anyone heard of Rev. S. E. Colwill?
Thank you,
