Looking for one of our centenarians (Novato's 103 year old Signe Bostrom Nielson) in the 1920 census, I know she was in Petaluma, having arrived from Sweden in 1914 and married in 1920. I find her two (citizen) brothers, and her forthcoming husband, but not her. Were (are) people here with a tourist or immigrant visa normally included in the census'? Jerry D. Moore
