Matheson of South Carolina OR Georgia

Looking for relatives of Christopher Stoney Matheson who married Thomas Ellen Baker (a member of the Thorpe family). Had 2 children, Murdock Pratt and Irene (Irene married Lacy Sheffler - ?sp?)while living in either Savannah or Darien, Ga. Ellen died in or shortly after childbirth with Irene; children were raised by maternal grandparents, I believe in Darien. Stoney fought in the Spanish American War and was an itinerant bookkeeper by trade. Murdock Pratt Matheson was my grandfather.
