The Berwick family owned what is now Garret and Johnson plantations. They are located about 6-7 miles south of Centerville on Highway 317 (Bayou Sale Road). Berwicks were also associated with Ellerslie Plantation south of the Intracoastal Canal on the same road. They also owned land near Berwick, LA. If you give me some names and dates/years I may be able to find the place where your family lived.
