I am looking for clues regarding the parents of James McClain (McLain, McLean, McClaine, McLane, MacLean) who married Isabella (Isabelle or Isabel) Varner January 13, 1840 in Greene County, OH Ohio. James was born in 1817 or 1818 in Maryland MD, and according to later census records both of his parents were born in Maryland. Isabella Varner was born in Maryland in 1818 or 1819, and her father's name may have been Anthony Varner. They had the following children:
William P. or William B. b. 1840 in Ohio Elis (Elisabeth or Elizabeth) b. 1841-1842 in Ohio Stephen (Steffan) b. 1843-1844 in Ohio Margaret b. 1845-1846 in Ohio John b. 1850-1851 in Ohio James b. 1854-1855 in Ohio Mary (or May) Bell b. 1856-1857 in Ohio Jennie b. 1848-1849 in Ohio, but not listed with family on 1850 or 1860 census (Listed in 1870 with family).
According to census records, the family lived in Beaver Creek OH (1840), Xenia OH (1850), Spring Valley OH (1860) then migrated to Spring Grove Illinois IL in Warren County by 1870. Isabella died between 1870 and 1880 (1874 possibly). Most of the family later moved to Caldwell County Missouri MO by 1880. James (the father) lived the rest of his days with his son Stephen and died in 1905 in Gomer, MO Caldwell Co.
Any help that could be offered would be appreciated.
