I saw your message and thought how helpful it would be for me to get more info on my ancestors, so here is some information, but not much. it has been difficult for me to find info on Elizabeth, also.
She was born abt. 1750/1760. Joseph Ramage married Elizabeth Bourland, a daughter of William and Mary Bourland. The Bourland family lived in what is now Laurens County, South Carolina. Joseph Ramage received a 239 acre grant on 2 April 1786, in what is now Laurens County, South Carolina. Capt. Joseph Ramage and his wife, Elizabeth, lived on this land until Capt. Joseph Ramage died in 1825. Following his death, Elizabeth moved to nearby Newberry County, South Carolina and lived with her son, John Ramage, and his family. These are their children: James Ramage, John Ramage, Mary Sparks, Jane Bonds, Robert Ramage, Elizebeth Wesson, Jesse Ramage, Joseph Ramage, J. L. Ramage, and Rebecca Dabage."
that is all the information i have found so far. If i find more i'll kepp you update. feel free to e-mail me any time for info.
