Colonial family base
The family history becomes documentary rather than purely traditional in Chester County, where tax, land, and probate references identify the household associated with the immigrant-line John Poston.
Land and probate record
The revised genealogy cites a land patent for approximately 274½ acres in Fallowfield Township and a 1745 will later proved in Chester County.
Southward migration
The 1766 sale of the Pennsylvania homestead is used as the documentary marker for the later family’s movement south toward the Carolina interior.
