Does anyone have any information on the Hans Andrew (H.A.) and Randi Mikkelson family? OR the H.A. and Anna Mikkelson family?

Randi was my great grandfather, Tollef (T.T.) Emmerson's only sister. H.A. & Randi had 2 children that died in infancy:
1.Oscar (1879-1880)
2.Johanna (1886-1888)

H.A. & Randi then adopted my great grandfather's infant daughter around 1893 when his wife died after childbirth. They called her Marie. She grew up to marry John Edward (Ed) BREUNING & subsequently moved to Cass Lake, MN. Randi died at the young age of 42 in 1901 when Marie was just a young girl.

H.A. then married Anna FOSS in 1902 & they had 2 children:
1.Vera Albiona (b.2.29.1904)
2.Homer Angelo (b.9.13.1909)

As far as I know, Vera married Wilford NELSON around 1907.
