Henthorn Family Genealogy Forum
(to Elizabeth): I noticed that you didn't list a place of birth for anyone in your line, or any general time frame, so I'm not sure where to help you look for Henthorns, or when they existed.
Therefore I only have this to offer;
In my recent searchings for my line, I happened across an Adam Henthorn of Illinois (McClean Co.) 1850 census report, who is aged 55, with sons John age 15, (unreadable male) age 12, Wm Allen age 10, Margaret age 6, Mary age 16, and a wife with a name that starts with "S" but is unreadable, who is aged 52. This Adam is from OH.
RICHARD Henthorn's page is good, but it is far from containing all Henthorns, so let's all keep looking.
