Thanks for filling us in on the Scotch-Irish. I have been going over censuses lately and the number of estates on which the manager/overseer was both born in Ireland and English/Anglican/Episcopalian in religion is very great. Nearly half perhaps.
The cemetery behind St. John's Anglican in Christiansted is full of riches but, unfortunately, dangerous. My own experience may be helpful. Thinking that early in the day would be a great time to look around, I walked up to the cemetery one morning at about 6:00 AM . You must enter it through a side street, and already at that hour the corners were filling up with guys without much to do. Upon leaving the cemetery about a half hour later, one of them approached me menacingly with a long knotted rope. When just a few yards away, he snapped it at the ground in front of my feet. That was all, but it was enough. I didn't think of going back.
All this is especially unfortunate because there is so much history to be learned in that cemetery. It has both public and private (church members) sections. I don't know if a listing of all burials exists. Perhaps, someone knowledgeable about that can tell us. The Research Library at Whim does have copies of records from St. John's, including burials, although I can't say how complete they are.
Have fun, but don't go to the cemetery by yourself!
