It looks like Asel was in MB in 1901 although his name is spelled Arel subdistrict:Dufferin, Lisgar District #7, b-14 Microfilm # T-6432
So the marriage should be in Manitoba on would imagine, unless they did something like went to N. Dakota to marry. At any rate, I can't find it either.
It also looks like he died shortly afterward, because "Emma" is listed as Jessie in the 1911 census in Kamloops but is widowed andwith her sons. Name: Asel Craddock Place Kamloops Reg. Number:1910-09-199958 Date: 1910 3 20 (Yr/Mo/Day) Age:37 Event:Death Microfilm #: B13111(GSU # 1927139)
