I too am looking for anything on the Christiansons from Gull Lake and area. My father is Phillip Edward Christianson and was born in Gull Lake 1930 . His parents were Margaret Helen Muller and Malvin Christianson . Malvins father was Ole Christianson who immigrated from the USA. South Dakota around 1910-11. My father has passed away before I could ask him any family history. To my surprised by reading about William Christianson owning a service station as it turns out my father owned and ran several service station throughout B.C. He was a very successful master mechanic.I was wondering if William and Ole are related in some way . I was also wondering how my father new so much about mechanics at such a young age.Did William show him the trade.?
