I'm researching Asahel Henderson. Ancestry.com has records for him in 1833 and 1840 in Michigan, and from 1850 - 1900 in Beloit. He served in the WI state assembly at lest from 1874-1879. He was married to Elizabeth, and they had two sons, Maurice and Clarence. Maurice was 17 in the 1860 census. Then A. married Catherine circa 1871. She is still listed in 1909 directory of Rock County Farmers. I do not know what happened to Maurice and Clarence.
I am not related, but doing property research in Beloit.
