Good chance that William Henry is related to my late father-in-law Clement Swearingen, son of Otis Olen Swearingen. Otis lived in Neponset Village, Bureau, IL in 1900-1910. They moved to Penn, Stark CO IL by the 1920 census, then to northern Wisconsin by 1930.
I'm assuming that you have an Ancestry.com subscription and can research using those records. If not, let me know and I'll see what I can find on your line.
