From Scott Bumbaugh:

!1880 census for Valley, Preston County, West Virginia.  It lists Jos. Clark (aged 40, England,
parents born in England; a preacher), wife Mary A. (aged 38, England, parents born in England),
daughter Martha (aged 14, England), daughter A. Jane (aged 12, England), son J. W. (aged 9, WV),
daughter Mary E. (aged 7, WV), daughter Ida M. (aged 5, WV), and son Walter S. (aged 1, WV).  I am
assuming that this Ida M. Clark is the same woman who later married George Walter Hardman.
