166 LETTERS FROM THE REV. WM. DERHAM, D.D. miles from him, than are given here. These unfortunately have no doubt been destroyed during the lapse of time which has taken place since they were penned. Dacre Barrett was the eldest and sole surviving son of the Honble. Richard Lennard, only son, by his second wife, of Richard Lennard, Lord Dacre. Dacre's father took the name of Barrett under the terms of the will of his kinsman, Edward Barrett, Lord Newburgh, on succeeding to Belhus, which house was built by Edward's great-great-grandfather John, who died in 1527.
