Yes, Halstein Lade and wife Inger lived in Queen township (on a farm) near Fosston, Polk Co., MN, and came with the children you mention in 1886 to the USA from Syvde, Norway.
Regina was Inger's daughter by a previous marriage to a Gullick Sordal who died in Norway. My grandfather, Saebjorn Gotfred Lade (6 Jan 1886-13 Mar 1922) was a small baby when they arrived in the US. He died of nephritis due to complications of the flu epidemic at about age 35. After they came to the US Halsetin and Inger had a son Paul Lade (4 Mar 1888-3 Nov 1889), Halfdan Halsten Lade born about 1890 who died at about age 22 of TB, and Ingvald Lade (About 1894-Nov 1966. Ingvald inherited the farm and was a "bachelor farmer" and I remember many visits to the farm as a child.
