"The county of Linn is so named in honor of a distinguished senator of the United States, the Hon. Louis F. Linn, of Missouri. It is situated centrally in the eastern half of the state, and from fifty to sixty miles west of the Mississippi river. "It was defined by act of the Territorial Legislature of Wisconsin, at its session of 1837 and '38; that Territory then including the whole of Iowa within its jurisdiction. The county limits were the same as they now remain, consisting of twenty Congressional townships, containing an area of 720 square miles. It is bounded on the north by Buchanan and Delaware counties, east by Jones and Cedar, south by Johnson and west by Benton. It is now divided into nineteen civil townships, as follows: Bertram, Boulder, Brown, Buffalo, Clinton, College, Fairfax, Franklin, Fayette, Jackson, Linn, Marion, Maine, Monroe, Otter Creek, Putnam, Rapids, Spring Grove, and Washington. "The county was duly organized by the Board of County Commissioners at their first session held September 9th, 1839, at the farm house of Mr. James W. Willis, one-half mile north of the present town of Marion. The board consisted of Samuel C. Stewart, President, Peter McRoberts, and Luman M. Strong, Commissioners; Hosea W. Gray, Sheriff; and John C. Berry, Clerk. "This Board also approved the selection of the county seat, which they ordered to be called Marion; divided the county into election and road districts; and appointed Andrew J. McKean and William H. Smith, Constables. Of the officers and persons above named, but two, Messrs. Gray and McKean, remain residents of the county, the latter being the present Clerk of the District Court. * * * * * "The first white settler in this county was John Mann, who erected his cabin on Upper Big Creek, in Linn Grove, in the month of February, A. D., 1838. He was an emigrant from the mountainous region of southwestern Pennsylvania. He was an honest, industrious, unlettered, rude sort of man. Subsequently he built a small flouring mill. A great flood in the spring of 1851 carried away his mill and himself together. The unfortunate man was drowned, and his body recovered only after several days had elapsed. The flood was unprecedented, and was thought to have been caused by a water spout. The Little Creek is said to have risen twenty feet in about as many minutes.
