I'm looking for information on my great grandmother, Jona Soffia Johnson (born Johannsdottir). She usually went by Soffia or Sofia rather than Jona. She was born around 1883 in Iceland, emigrated to Canada with her family in 1883 or 1888 (the Census records conflict). She married Magnus Johnson/Jonsson on September 20, 1902 and settled in Winnipeg, Manitoba around that time. She died on October 26, 1961. Her obituary says that she was survived by her brothers John Johannson and Sigfus Johannson (both of Lundar, Manitoba) and by a sister "Mrs. S. Dalman" of Vancouver, British Columbia, Canada. I found a military record of someone that I think might be her brother Sigfus, but I can't confirm that for certain. Other than that, I know nothing about her siblings or her parents.
Can anyone point me in the right direction?
