Simm, John Rudolf and Simm, Alfred from Sweden to Bellingham,Whatcom,Washington

[Eva Kristina Weingut]

Looking for my relatives, the brothers John Rudolf Simm born  July 19, 1878(Swedish name Jonas Rudolf Söm) and his brother Alfred Simm born December 19, 1885 (Swedish name August Alfred Söm) and any relatives of theirs. The emmigrated to the US in 1905 and settled down in Bellingham, Whatcom/Washington. It has been proved that Alfred had children.  
Also looking for their sister Bertha Simm (married Mauer)in San Francisco and her grandchildren in California.
Has anybody heard of the name Simm (or sometimes Sims/Som/Somer) from Sweden???
 
Thanks
