I believe I found your ancestors grave. The surname could be spelled differently "Holand" but the grave is really worn and it could be him. He is located behind the church outside, straight ahead towards the burning bowl area. He's on your left on in a ground level grave with a small stone wall around him. His grave has several bolts holding it down. When I can figure out how to post a picture here I'll send you a picture of his grave.
Sorry I can't help But,perhaps someone at the Charleston Historical Society on King Street can steer you to an answer. Good luck.
Donna, we do have limited records of cemetary inhabitants. A lot of our records were lost during the civil war. I don't know if there is anyone who officially helps with genealogy, but we do have a records ministry. There is also a blueprint of the cemetary from the 1800's on the wall in the sanctuary . We are closed for the hurricane but if I remember I can look up your ancestor on that. You can also contact the church directly through our website.
