THEYDON-GARNON, (Essex) 1 m. from Epping, the ancient seat, if not the manor of the Gernons, was held in the R. of James I. by Sir Sam. Dun, dean of the arches, as parcel of the duchy of Lancaster. In 1660, Sir Robert Abdy, Bt. was Ld. here, from whom it descended to Sir Robert, his grandson. The late Mr. Archer had a seat here.
