I believe my great grandmother Anna Wilhemina Jarvinen born 1876 in Finland was a sister to your grandfather Oscar. Oscar and Anna had at least 2 other siblings, Otto and Kalle (Charles). Anna came to Canada but had relatives in the states. The names of Oscar's children that we were aware of were Sylvie, Lyna and Toivo. Is there a connection here? Any info would be very welcome.
