Richard, I know you asked for other help, but I have a bit of info on this for you. The name is also spelled Choconicla. The locations of all of the Apalachicola reserves are shown on the original Jackson County land plats. There are copies of these in the Property Appraiser's Office in Marianna. A description of the town can also be found in Captain Hugh Young's memoir of 1818. If you don't have a copy of this, let me know and I will dig mine up for you. Best, Dale
