Gunns Mill, Abenhall, Near Mitcheldean, Gloucestershire: Tree-Ring Analysis and Radiocarbon Wiggle-Matching of Two Roof Trusses
Author(s): Robert Howard, Alison Arnold, Bronk Ramsey, Dr G T Cook, Frances Healy, Ron Reimer
Dendrochronological analysis had been undertaken previously on samples from a number of timbers of Gunns Mill, Abenhall, Gloucestershire. Timbers from the north part of the building were dated by this method to AD 1681–82, while timbers from the south part remained ungrouped and undated individually. Six single-year samples of oak from the east queen posts of each of two roof trusses in the south of the building, GNM-A13 (truss B) and GNM-A11 (truss C), which had not been dated by dendrochronology and did not cross-match with each other, were subsequently the subject of radiocarbon dating and wiggle-matching. This analysis suggests that the timber for the east queen post of truss B was felled in the second quarter of the eighteenth century cal AD or later and that the timber for the east queen post of truss C may have been felled in the second quarter of the nineteenth century cal AD, although an eighteenth century date is also possible because of the irregularities of the calibration curve in this period. Both were later than the AD 1681–82 timbers in the north of the building identified by dendrochronology.
