looking for information on Theodore Ostrom (My great grandfather) born in Elbo Lake, Minnesota in 1880, d 1961. Was married to Anna Louise Anderson (b 1879).

Had 7 children: Harold - b. 1908, D 1986 (my grandfather), Leonard (b 1911), Evelyn (b 1913), Toline (b 1914), Laurence (b 1916), Chester (1919) , & Lyle (1924)

Believe Theodores parents were Olaus Amundson Ostrom and Toline Paulson, but both ancestry I found had them being born in Norway. 1930 census records listed Theodores and Anna's ancestors from Russia, and both of my grandparents (Frieda Riele) spoke German, not Russian.

Any info would be appreciated.
