ALTERNUN MANOR

Identity: confirmed — The registry record names ALTERNUN MANOR and places it in Altarnun, Cornwall. Alternun/Alternon are documented historical spellings of Altarnun. Local historical evidence identifies Trelawny in Altarnun as the original seat of the Trelawny family, who were later described as lords of the manor, making the Trelawny site the best-supported surviving manorial centre for this record.
Representative point: 50.61725, -4.52538
Basis: supported_manorial_centre — Trelawny farm/barton in Altarnun, identified in local historical accounts as the original Trelawny seat, with a former deer park; the Trelawny family is documented locally as holding the manorial lordship. Coordinates correspond to the mapped Trelawny farmyard/site.
Point confidence: medium
Boundary status: representative_point_only
Boundary period: medieval to early modern, undetermined
Boundary confidence: none
Boundary basis: The available evidence establishes the manor's association with Altarnun and the Trelawny manorial centre, but does not provide a manor map, survey, rental plan, explicit perambulation, or other reliable evidence from which the historical manorial perimeter can be reconstructed. The modern parish boundary, which is much broader and not demonstrated to equal the manor, has therefore not been substituted.

Warnings / uncertainty:
- The manor's exact territorial extent remains unestablished from the available online evidence.
- Trelawny is used as a supported manorial-centre proxy, not as proof that the surviving farmyard marks the complete medieval or early-modern manor house footprint.
- No boundary polygon should be injected without further archival evidence, such as a manor survey, estate map, rental with parcel descriptions, or boundary perambulation.
