It is bounded on the east by Jackson County, on the north by Eau Claire County, on the west by Buffalo County, as well as by Winona County across the Mississippi River in Minnesota. The area belongs entirely to the Mississippi system, and is separated into three distinct divisions, the Trempealeau Prairie Region, the Trempealeau Valley Region and the Beef River Region. The county was created Jan. 24, 1854.

The Heydon family name comes from the town of Heydon, in Norfolk, England, the locality of their original estate. Thomas de Heydon (ca. 1185-ca. 1250) of Heydon was a justice in Norfolk County. His son, William Heydon (ca. 1220-1272) succeeded him in the estate and was the father of John De Haydon, the judge, and ancestor of the Devon line. The author assumes that John, William, and James Heydon, three brothers, the immigrated ancestors of the American lines, who appeared in Boston, Dorchester, and Charlestown, Massachusetts, in 1630, were sons of Gidoen Haydon, of Cadhay, of the Devon line. Some of their descendants spell their name "Hayden."
