From the 1882 and 1907 Pottawattamie County Histories
The early history of Carson township is identical with that of Macedonia of which it was a part. The egg from which both the township and town hatched was Loshe’s mill. J. Z. Losh had been conducting a mill for Mr. Stutsman when in 1856, his eye fell upon a mill site several miles above that, near the south line of Sec. No. 3. It was here he erected what long afterwards was known as Losh’s Mills, and not long afterward, the new town of Carson sprang into existence only a short distance east of the mill.
Eventually, Carson claimed the post office and by 1881, became an incorporated town.
With the opening up of the branch roads from Hastings and Avoca, both township and town rapidly gained importance. The township is small, having but twenty-four sections, twelve of which were detached from Macedonia and as many from Belknap. It is named in honor of a prominent railroad official.
Early township officers were: trustees, Claus Hartz, C. H. Coyl, and A. F. Stone; clerk, F. G. Weeks; assessor, T. W. Dungan; justices of the peace, D. McMillan and Z. F. Linville; constables, A. A. Faley and Thos. Brack.
