While carrying out fieldwork in the Annan area on behalf of the Scottish Development Department my attention was attracted by a remarkable series of Renaissance buckle quoins at Hayknowes farm — at first sight puzzling, since the architectural style of Hayknowes otherwise indicates a building date of somewhere around 1800. These quoins are built in to each of the front angles of the house, and rise to a height of about five feet. And nearby, at Newbie, on the spot identified by the Ordnance Survey map as the site of ‘Newbie Castle’, a single similar quoin exists, built in to one angle of a nineteenth-century cottage.
A clue to the puzzle was provided by the coincidental re-cataloguing of part of the Annandale family archive by the National Register of Archives (Scotland) [NRA(S)], whose secretary drew attention to the existence of a body of material relating to the construction in the later 1650s of a house at Newbie for the Earl of Hartfell. One surviving receipt in this group, for having produced a sundial, is from John Mylne, King’s Master Mason, and dated 1655. This document is of particular interest since, by linking Mylne’s name with Newbie at the same time that a new house, or an addition to a house, was being built there, it indicates the possibility of Mylne having also been involved with the design of the building at Newbie.
