In 1846 he took his family to WI, settling at Burnett, in Dodge County, near Rolling Prairie, where he had previously purchased 80 acres of land. later he added to this 100 acres more. In 1856, he built a fine stone residence, which was the family home until the death of his wife. He added to this a large stone barn.
