Built in 1862, it is associated with Swedish settlement in Iowa. Carl Cassel came with his father and the first group of immigrants to the Iowa Territory in 1845. They settled in a place they called New Sweden. Anna Dalander led another group of immigrants the following year and intended to settle in the same place, but they took the wrong river and ended up in Boone County. They named their settlement Swede Point, which was later renamed Madrid. Cassel married Dalander's daughter Ulrika in 1848. He and his brothers-in-law operated a grist mill. He also farmed and was involved in local politics. This house was located on the edge of his farm and the town. Cassel probably lived here until his death in 1902.
