Based upon the information George and Alan have provided, I would suggest that you contact the staff at Old Blandford Church in Petersburg, Virginia. Since he died in a military hospital in Petersburg in 1864, they might actually have some record of his burial. I know from a previous visit that they have a notebook with the names, etc. of the known Confederate dead.
From http://www.craterroad.com/memorialhill.html >>>Besides the reburials on Memorial Hill, many thousands of soldiers from other battlefields were brought to Petersburg for hospitalization from 1861-1865 and died here. Many of these were buried in Blandford Cemetery, a record of whom is kept in the church, showing their native state, their rank, age, cause of death, and beside whom buried north, south, east and west.<<<
