I'm afraid I can't help. I have been aware of this Samuel D. Carrick without knowing who he is. Since the marriage bond of (the soon to be Reverend) Samuel Carrick to his first wife was posted in September 1779, it would seem unlikely that Samuel D. Carrick was his son. I don't have a list of all of The Reverend Samuel's children--is there any descendant out there who does? I can only speculate that Samuel D. is likely to be a nephew. This extended family used the same given names over and over again--a nightmare for us now.
