Pennsylvania household
John Poston II inherited the Pennsylvania family setting established by the earlier John Poston and married Margaret Baldridge, linking the Poston line to the Baldridge and Holmes families.
The 1766 break
The published histories treat the September 1766 sale of the Pennsylvania homestead as the decisive break from the family’s Pennsylvania phase and the beginning of the southward migration.
Evidence limits
The exact sequence of the family’s movement after the sale is not reconstructed with equal confidence in every source. The published family history preserves that uncertainty rather than presenting a single unsupported itinerary as settled fact.
