The Cedars, 1A & 3 New Road, North Walsham, Norfolk: Tree-Ring Analysis and Radiocarbon Wiggle-Matching of Oak Timbers
Author(s): Alison Arnold, Robert Howard, Cathy Tyers, Michael Dee, Bisserka Gaydarska, Peter Marshall
Dendrochronological analysis was undertaken on two samples taken from principal rafters at this building. The two principal rafters are shown to be coeval but the two-timber site sequence, NHWCSQ01, could not be securely matched with the reference chronologies. Radiocarbon dating was undertaken on five single-ring samples from a timber in the site master chronology. Wiggle-matching of these results suggests that the final ring of this site master chronology formed in cal AD 1648–1668 (95% probability) or cal AD 1652–1662 (68% probability). This is compatible with the tentative dating produced for the site master chronology by ring-width dendrochronology, which suggests that it spans AD 1589–1656. The tentative tree-ring date can only be accepted because it is supported independently by the radiocarbon wiggle-matching, but together they suggest that the timber represented in site master chronology was felled in AD 1657–80DR.
