As far as I know, there have only been a couple of people named, Amos Henthorn.
The Amos Henthorn who lived in Henry Co., IA was born 16 Mar 1820 in Clark Co., IN.He married Elizabeth Sharp.Most of their children were born while they were living in Henry Co., IA.
This is the Amos Henthorn for whom, Roy and Norma (Latham) Henthorn of Bethany, OK published a genealogy many years ago.The document is sometimes referred to as "The Amos Tree."There is a copy on film from the LDS Library in Salt Lake City, UT.
I have keyed all of the information from this document into my genealogy program and added to it.
