Donna, you are a jewel! No, I didn't have info on 1850 census of John Taylor. Actually I have seen no census info for Williamson Co. Will appreciate anything you run across on the Marlins, Taylors or Locks. I am curious to know if possibly Thomas Lock (who I have a hunch is Margaret's father) might have died in the cholera epidemic of 1854 that killed George Marlin and others in his family. I was privileged to attend a Taylor reunion at the Lynn Cemetery on Natchez Trace last year and see John's grave. No one knows where Letitia is buried or exactly when she died - somewhere between 1861 and 1865. I met several cousins of Taylors and 1 cousin descended from James M. as I am. Don't mean to bore you, but I am so excited to get these tidbits of clues from you. Judy
