The Delventhal-Miller Farm was established in 1892 when brothers John and Herman Delventhal purchased two half sections of land in Weld County, near Brighton. Herman and his wife, Mary, eventually ended up with the north half of the farm, and, in 1945, passed on 30 acres to their youngest daughter, Esther, who had just married Martin Miller. The Miller family is also receiving the National Trust's historic structures award for the preservation of several buildings, including the original house and barn.
