Captain A.J. Jones Company, Pamunkey Artillery, Virginia Heavy Artillery had 24 pounder smoothbores and 20 pounder Parrotts. The unit was from New kent County, VA. Several officers and cannoneers are buried at Mt. Olivet Church between State Rt. 249 and State Rt. 60 in New Kent County. It's just down the road and I can't think of the route number. It is called Olivet Church Road.
