DERHAM, (Gloucestershire) or DURHAM, or DYRHAM, on the E. side of Pucklechurch, is full of springs that supply the r. Boyd, and famous for the remains of large ramparts and trenches in the field of battle, where Ceaulin, one of the W. Saxon Ks. obtained a great victory over the Britons. The manor bel. formerly to the Russels; from whom it came, by the female issue, to the Dennisses; then to the Winters; and lastly to Will. Blathwait, Esq; son of the secretary of state to K. Will. III. who built a fine seat near the Ch. with curious gardens, walks, and water-works; and adjacent to it is a large park and warren, with a lodge. Sir Will. Dennis and others founded a guild in this p. in 1620.
