My information says that Dr. Francis Fielding Calmes died in 1865 and is buried in Laurens, SC. He never moved to Mississippi. His son, Fielding Calmes, I belive is who the slave referred to as Felix, aand he did move to Mississippi. "Felix" would have been around 30 at the time of the Civil War. This oral history was taken in 1937, so that also makes it unlikely that she could have been referring to Francis, Sr. In addition, she refers to "old Dr. Calmes," as helping treat her when she was sick. These men are both descendants of the Marquis de la Calmes, an aide to General George Washington and a French Hugenot.
