Okefenokee Swamp
Longtime residents of the Okefenokee Swamp, "Swampers", are mostly of English ancestry. Due to their isolation, the Swampers used Elizabethan phrases and syntax well into the twentieth century. The Suwanee Canal was dug across the swamp in the late nineteenth century in a failed attempt to drain the Okefenokee. After the Suwanee Canal Company's bankruptcy, most of the swamp was bought by the Hebard family of Philadelphia, who logged cypress from 1909 to 1927. Several other logging companies ran railroad lines into the swamp until 1942; some remains are visible across swamp waterways. Most of the Okefenokee Swamp is included in the 403,000 acre (1630 km²) Okefenokee National Wildlife Refuge.
