whom, in the R. of K. John, obtained a Mt. here. It afterwards passed, by marriage, to the Staffords; who held it down to
Cha. I. when Sir William Howard inherited it, by marrying Henry Ld. Stafford's only daughter and heir, and was created
Visc. Stafford. It came lastly to the Thynnes family, by the marriage of Sir John Thynne, an ancestor of Ld. Visc.
Weymouth, to a daughter of Sir Rowland Hayward.
