The information I found at the Historical commission in Darlington, SC says that the children of John Osban and Mary Byrd are (1) Robert (2) Mary Caroline P., born 6 Dec. 1836; died 23 Jun. 1905; m J. Thomas Chandler on 5 Mar 1857. I have no information about any children. (3) Anne E. (4) Joseph Wheeler (my line) (5) Olivia Susan.That is all the info I have at this time. I do not have any documentation showing that Mary Caroline P. is the dau. of my John.I wish I had more. Can you give me any more information about your Mary?
