Unzicker-Cook House, 2975 Oxford-Middletown Road, Milford Twp. (at Hamilton-Richmond Road, Ohio 177), was added to the National Register of Historic Places in 1974. The web site of the Ohio Historic Preservation Office of the Ohio Historical Society says: "Daniel Unzicker (1798-1863) came from Bavaria, Germany, with his wife, Magdalena Kahn (1803-1880). They were married in 1821 in Germany and shortly afterwards emigrated first to Canada and then to Pennsylvania. About 1828 they moved to Butler County, and settled at Overpeck. Later they moved to 80 acres in Milford Township which they had bought for $300.
When the Unzickers moved to the land, which was a tract of school land in Section 9 of the township, there was a clearing with an old log cabin and stable. Unzicker continued to improve the land with the construction of several stone buildings. He farmed the land and increased his holdings to 160 acres. Daniel Unzicker and his wife were Mennonites. At the time they moved there as an influx of Mennonites into Butler County from Canada and Pennsylvania. Many settled in St. Clair and Madison townships. He was also a preacher and both were active and faithful members of their church. They had 13 children. All of the children married and became farmers except Elizabeth who was a school teacher. Of the other children, Peter was a stone mason and probably helped with the construction of the house and farm buildings. Daniel became a shoemaker and David operated a still on the property about 1839. Daniel Unzicker was also an active Democrat and was highly respected in the community although he never held public office."
The OHPO says "the whole complex is the result of rational site planning. Although the buildings are simple in construction and plan, they provide necessary shelter and take advantage of local building materials and the sloping site. The house is built close to the hillside and opens to the south and east, so it is protected from the harsh winter weather which comes from the north and west. The springhouse used the spring to keep its interior cool and moist. The smokehouse is largely exposed for good ventilation. It shows planning based on necessity and practicality."
