In 1900 Carroll Co AR census James is listed as Jonas G Allen born 1823 TN. Found him in Jackson Co TN in 1860 and Monroe Co KY in 1870. His wife was Rachel born about 1824-27 TN. They had at least 10 children: George W-1850, TN Lavina J-1852, TN James McF-1853, TN Mary L-1855, TN Sarah Elizabeth-1856, TN Henry R-1859, TN Alexander S, 1862, KY Franklin W, 1863, KY Rachel, 1865, TN Clary C, 1867, TN
In 1860 Jackson Co TN there is a William Allen living with them who is 18 born TN,,,could be a son of Jonas??
