I researched the American Local History Network for Clark County,Wisconsin for information on the Heaslett/Fuller line. The U.S. census database at Heritage Quest Online is a valuable source for every line I have traced so far. Other detailed information was provided by relatives or was obtained from a printed source at the Newberry Library in Chicago.

This site is an excellent source for information about Company C of the 3rd Wisconsin. Company C fought in many of the major battles of the Civil War including Gettysburg and Antietam.
