The 1810 birthdate for James A. Rowell is due to the tombstone, according to his memorial on Find a Grave.  In 1820, James Rowell (James A. Rowell's father) is listed as having 1 male under the age of 10 living in his household. This was the only male other than the head of household himself living in the house. In 1830, James Rowell is listed as having 1 male between the ages of 5 and 10 living in his house. This is the oldest male living in the house other than the head of the household himself. Taken together, this means that James A. Rowell was a newborn infant in 1820, and that he was just shy of his tenth birthday in 1830.   James A. Rowell lived and worked as a farmer in Blackshear, GA in 1860. At that time, he is recorded as being 41 years old.  By 1870, he and his family had moved to Taylor County, FL, where he and his eldest son David continued farming to support the family. In 1870, James A. Rowell is recorded as being 50 years old.  By 1880, 63-year-old James and his family had moved to Wayne County, GA. Also by 1880, his daughter Celestia Hester Ann had gotten married, and lived in the same district of Wayne County with her husband and children.  In 1900, 80-year-old James and his second wife, Susan, and their children were living in Charlton County, GA.
