Much can be found already written about Mr. Ackerman in any of the published histories of Dodge County or Beaver Dam, Wisconsin.
For example, this from the 1880 History of Dodge County:
Son of John D. Ackerman; born in the city of New York on the 22d day of June, 1804. In the summer of 1839, he made a tour of observation thorugh the Territory of Wisconsin, extending his observations as far as Lake Emily. Returning to New York, he, with his wife and eight children, and Henry Stultz, wife and three children, took passage on a Hudson River steamer for Albany, on the 1st of May, 1840. From Albany they went to Buffalo on the Erie Canal, and then embarked for Milwaukee on board the steamer Illinois, commanded by sturdy Capt. Blake, a name familiar to thousands of pioneer emigrants to Wisconsin, and a famous man in the early history of lake navigation. From Milwaukee they went to Fox Lake in emigrant teams. After three days of fatiguing travel, they reached that point on the 24th of May. From Fox Lake they removed to Lake Emily, where they spent the first summer, under a clear Wisconsin sky, and surrounded by all the charms and enchantments of its beautiful scenery. In the fall, they returned to Fox Lake, and there spent the winter of 1841 and 1842. On the 22nd of February, 1842, Mr. Ackerman moved his family to Beaver Dam, and took possession of his log cabin, which he had previously contracted with Mr. Mackie to build, and there resided till the date of his death, March 9, 1867.
"Abraham Ackerman, one of the first settlers of this city, died very suddenly, though not unexpectedly, on Saturday evening last, by a stroke of palsy, a disease with which he has been afflicted for several years. He died at the age of 63 years, having lived in this city for the past twenty-five years. He was an honorable, upright, benevolent Christian gentleman, respected by the entire community, and a man without enemies. His funeral sermon will be delivered by Rev. J. J. Miter, at the 1st Presbyterian church tomorrow morning." - found in the Beaver Dam Argus second week of March, 1867.
