I am doing research on my grandfather's line, Gust Dahlstrom, son of Halvard (Larsson) Dahlstrom. I just saw your post. Thank you for the addl generation.
The family moved to Turlock, California. There is an older daughter, Mary Lundell who moved to CA first. The rest of the family followed late 1890/early 1900s. Lars was also called Louis(even on the death record). Per was called Peter and died in MN 1889.
The Turlock Historical Society put out a periodical, The Turlock Pioneer. In Spring 2000, vol 2, no. 1, is an article on the family with pix of the family, including grandchildren. From this article, there was another daughter who died in infancy, but I have no name.
What documentation do you have for the names of Halvard's
mother and father and sibs? I have Halvard born in 1838,
death date 1930, buried in Turlock Memorial Park...my parents are also buried there.
