I am one of the s.c. descendants of Simpson/Remer. My great grandmother was Emmie Simpson, mother of my paternal gf James Milling Cathcart. There is more info on the Rev. Simpson in a book called YESTERYEARS- the heritage and history of the First Presbyterian Church in Anderson, S.C. I will look more into Mary Remer's history,apparently she was a very brave woman during the Revolutionary War.
