Originally a loosely organized community known as Snake Prairie and later as Eagle Branch, Rosanky was settled and developed by German immigrants in the mid-19th century to serve as a trading point for livestock operations. It was renamed in 1893 for Edward "Ed" Rosanky (1851-1906), a prominent Prussian immigrant who settled here in 1854, in appreciation for land he donated for a railroad depot. Located in a rural area about a mile from the town center, Rosanky Cemetery is the burial site of more than 125 residents and military veterans. The earliest known grave is that of Katy Schubert, an infant who passed away in 1908. George Meuth (1815-1894) and his wife, Mary Eichorn Meuth (1828-1894), originally owned this land. George and Mary's son, Andreas "Andy" Meuth (1861-1933), and his brother-in-law, August Adolph Grohman (1854-1940), husband of Andy's sister, Catherine Meuth Grohman (1857-1939), verbally committed to allocate one acre of the land for the cemetery. The cemetery came about formally in 1938 when Walter C. Grohman (1895-1961), son of August and Catherine, officially deeded this one-acre tract of land to the community of Rosanky. Headstones in Rosanky Cemetery reflect familiar names in the community such as Behrens, Darnell, Echols, Fogle, Grohman, Meuth, Ringer, Stall, Ross, Schubert, Smith and Wendt. Many people with these surnames, having family ties by marriage or blood, still live in the area. The cemetery is currently in use and is maintained by the Rosanky Cemetery Association, an organization comprised of descendants of those interred here.
