He was born around 1820 and immigrated from Norway. We do know there was a surname change during the immigration process but we haven't been able to locate any records indicating what that surname was. We believe he was married to a Susan A Branding. Their children were Anfin Olai Petersen (born in 1865 in Iowa), Lillian Petersen and Betsy Petersen (we believe both were born in wisconsin). Anfin was married twice. His wives were sisters. Selma D Brenson (Norway 1873) and Victoria Caroline Brenson Petersen Anderson (Unknown, 1883).
His children with Selma Brenson were:
Frances F Petersen (1895)
Herman E Petersen (1897)
Selma died around 1900
His children with Victoria Anderson:
Selma D Petersen (1903)
Lillian Petersen (1905)
Amanda Petersen (1909)
Edwin A Petersen (1912)
Conrad Petersen (1913-2006)
Joy C Petersen (1916-2005)
Victoria remarried after Anfin died in 1920. She married a Evald H Anderson and resided in Duluth, MN.
I'm looking for any information anyone may have on any of the people mentioned above.
