A. C. Dodge was appointed the first registrar of the land office at Burlington, and George W. Jones the first surveyor-general of Iowa. One of the surveyors-general in the early '40s was no other than Judge James Wilson, of Keene, New Hampshire, a son of a Revolutionary soldier, and himself a lawyer of more than ordinary ability, a judge, and at one time a member of congress. He was appointed by General Harrison, an old friend.
At the first convention which met at Burlington in November, 1837, for the purpose of organizing a separate territory of Iowa, were the following delegates from Dubuque county, which, at that time, included a part of what later became Linn county: P. H. Engle, J. I. Fales, G. W. Harris, W. A. Warren, W. B. Watts, A. F. Russell, W. H. Patton, J. W. Parker, J. D. Bell and J. H. Rose. The convention in its petition to congress asserted that there were 25,000 people in that portion of Wisconsin Territory known as "The Iowa District;" that houses had been erected; that farms were cultivated, and still people could not obtain title to their lands, and asking that the part west of the river be set aside as a separate territory. This was one of the most important conventions held on what became Iowa soil, and congress at once took action to make such provisions as were thought wise and expedient.
Linn county was established by an act of the legislature of the Territory of Wisconsin approved on December 21, 1837. The county was regular in shape, but four townships larger than its neighbors on the north and east, which were created at the same time. The boundaries received at this time have not been altered. The spelling of the name was Lynn, although it was spelled in the body of the act itself Linn; it took its name from Dr. Louis F. Linn, United States senator from Missouri, who was appointed to that office in 1833 and who was a friend and admirer of President Jackson, and much interested in the development of the west.
The eastern part of Linn county, perhaps one-third, had been part of the original county of Dubuque since 1834, the boundary line running from the southeast corner of the county in a northwesterly line a little to the west of the middle in the northern part of the county. Linn county then embraces within its limits two Indian land cessions. The eastern part was acquired from the Sac and Fox Indians by the treaty of September 21, 1832, known as the Black Hawk Purchase; the western part, or the other two-thirds, was acquired by treaty of October 21, 1837. The fourteen counties created by an act sub-dividing Dubuque county into new counties, which was approved October 21, 1837, were as follows: Dubuque, Clayton, Jackson, Benton, Linn, Jones, Clinton, Johnson, Scott, Delaware, Buchanan, Cedar, Fayette, and Keokuk. While most of these counties were established outright the wording of the act relating to Dubuque county implies that it was looked upon as the former county reduced in size, which was not correct, as this land from which these counties were laid out also included much of the Sac and Fox cession made after Dubuque county had been formed and laid out, and which county had not been ceded to the United States government.
