Debra,
Did you ever find the graves for Moses, Priscilla, James KP and Mary Bullock? I too have been searching for a while. In James KP Bullock's Civil War pension file, his date of death is given as July 18, 1881. I also know that Moses is still alive in 1883 when he is signing petitions to collect the Civil War pension for Jame KP Bullock's children who are living with him and Priscilla.
