Duck Pond Island at Sister's Creek
In September 1772, William Wilson was granted an island of seventeen and one-half acres bound on all sides by salt marshes. Wilson said the island was located in a branch of the St. Johns River (today Sisters Creek) called Duck Pond Island "near the Sisters." The tract may have been what is today called Shell Island, just north of Fanning Island and east of Sisters Creek. To avoid the shallow and dangerous sand bars at the entrance to the St. Johns River most ships traveled Sister's Creek--today the Inland Waterway--behind the safety of Fort George, Talbot and Amelia Islands to a deep water port at the St. Marys River.
