1880 census, Americus, Lyon Co. Kansas: J.F. Ryman, age 60, born in KY, father born in KY, mother born in VA wife Catherine, son Benjamin (age 26, born in Illinois), and other children
1870 census, same place John F. Ryman, age 50, born in KY, wife Catherine, son Benjamin F. age 17, born in IL
From the ages and birthplaces of John & Catherine's children, this family was in Illinois from 1857 until at least 1861 before they moved to Kansas. The censuses are pretty consistent that John F. Ryman was born in Kentucky. He is not to be confused with Thomas G. Ryman's father, John, who was born in 1819 in Tennessee and died in 1864 in Tennessee.
