I can't really give you an answer to this one, I know very little about Severine. She came to the US in 1905, but may not have stayed long after 1910. Severine was born in 1880 to Andreas Olson and his wife (this was not my grandmother, so no one knows anything about her). According to the information I have found, she had had 'infantile paralysis', a form of polio, and was 'crippled'. I think this is all I know. Let me know if you find anything.
On a side note, I have found that names run in families, husbands often had the same name as fathers, brothers, etc. Also, it is quite frequent for families to marry into each other. There are several connections that I know are fact and few maybes in just the few generations I've collected so far.
