Claim-to-source matrix
This matrix is intentionally conservative. It distinguishes what a source directly states from what has been reconstructed through genealogy or later interpretation.

| Andrew Poston gave land connected with the railroad development | Directly reported; deed not yet ingested | 1916 newspaper account | Acquire the recorded deed, conveyance, easement or right-of-way instrument. |
| Andrew Poston belonged to the Hugh Poston branch of the South Carolina family | Compiled genealogy / source trail | 2025 revised genealogy and lineage materials | Add the underlying family Bible, census, probate and deed evidence. |

How to read the status labels
Directly documented
A near-contemporary or primary source expressly supports the proposition.
Corroborating
A source independently supports part of the proposition or confirms a related fact.
Compiled genealogy
A later compilation supplies a research framework but should be checked against underlying records.
Verification in progress
The proposition remains a research target or is supported contextually but lacks the strongest primary record in this archive.
