Carrollton, on the Middle Raccoon River, was the original county seat before government moved to Carroll in 1869 for the railroad; it never grew past a small unincorporated crossroads. Roselle is both an unincorporated community and the name of one of the county’s 16 civil townships, so the two should not be confused when reading older county records.<\/p>\n
