Jean & Joel
On the IGI there is a User Submitted Genealogy stating that James Clark's father Ewan (or Hugh) was a twin , so looked for births and found
Hugh and William , christened March 21, 1791 to James and Jane Corlett in Lezayre.
On the US 1850 Census , there are two James Clarks in Marion County
One aged 22 , born England with the Coffee family , wrong age.
One aged 28 , born Alabama with the Craft family , age correct and he is a Tanner !!!
Cheers
