Arthur Clarkston and Sowell Carlstrom bring this segment of logging community members to an end. Big thanks to Jenny Tenlen at the Cowlitz Co. GenWeb Project for providing census information.
Arthur looks a bit unsure as he stands on a bench made from fir bows; he's dressed in Scandinavian clothing. According to the 1910 Cowlitz Co. census Arthur was 2 years old and the son of James (b. 1881) and Alma (b. 1890), both parents originally from Minnesota and probably of Swedish decent. This photo was likely taken around 1913-14 when Arthur was 5-6 years of age.
Sowell's portrait was shot professionally at Wedekin Studio in Astoria, OR. Little Sowell Carlstrom is 5 years old in his photograph. Poised with self-assuredness his sophistication seems doubt free. Based on information in the Cowlitz Co. census, Sowell was 3 years old in 1920. There are 5 other Carlstrom's listed, I'm guessing Sowell's parents were Arthur (b. 1891, Sweden) and Blanch (b. 1898, WA).
