National Register of Historic Places nomination: Haberkorn House and Farmstead, Sherrill, Iowa (1979)

The house “was built in 1870 by George Haberkorn and his father, Adam, the latter a stonemason and brewer who came with his family to the Dubuque area from Bavaria in 1844. Adam worked in the area lead mines, but the family income was augmented by a small brewery (which according to family tradition dates from soon after Adam’s arrival in this area) and the sale of bread baked by Eve Haberkorn in the stone oven near the farmhouse. Once the stone house was finished, its front room became a local tavern,” and for many years the polling place. “Adam Haberkorn died in 1890, his son George in 1906.” A rock-faced limestone house with a jerkinhead roof and a datestone over the door, “G. HABERKORN. 1870.”; the brewery cellar is a cave in the bluff. Still held by descendants in 1979. The nomination draws on family typescripts and Dubuque Telegraph-Herald articles of 1927 and 1960.
