I am a descendant of David Torrens' father, James Torrens and Mary Bovaird, and am looking for ascendency on each of these persons. I have David Torrens grandfather as being David as well, born about 1745. I have no information on Mary Bovaird's ancestry. David Torrens' sister Martha Torrens married John Buchanan. Their daughter Frances Margaret Buchanan is my grandmother. My mother's maiden name was Martha Torrens Greer, born in 1920. If you can be of any help to me in my search for ancestors it would be greatly appreciated.
