Moody of Prince George County VA

My great grandfather Robert E. Moody, born in 1839 in Prince George, died in 1889. I keep hitting a brick wall. I believe his father was George E. Moody, but am not completely sure. Robert E. was married to Martha Ann Moore and they had 2 children, my grandfather, Ashland and his brother Oscar Clarence, all of Prince George. If anyone has any more information or can confirm that George E. was Robert E. Moody's father, I would greatly appreciate it.
