Source Identification
Record: GNIS Feature ID 1225649 for Poston, South Carolina.
System: Geographic Names Information System, served through The National Map public names search.
Use: Place-name and entity identification for the Poston locality in Florence County, South Carolina.
Why This Source Matters
GNIS is the archive's most important public place-name identifier for Poston. It helps keep the site grounded in a stable federal record rather than relying only on informal map labels, family memory, or later narrative summaries.
How the Site Uses It
The GNIS record supports the identity of Poston as a named locality and gives the archive a durable identifier for maps, schema, and knowledge-panel references. It does not, by itself, explain the origin of the name or the older Ellison and landing-name history; those questions require newspaper, river, railroad, and family-history sources.
