Research Notes:

Rosteague. This is rightly interpreted by Mr. Hals, the fair or beautiful valley ; and its delightful situation doth fairly entitle it to this appellation.
This place, in the reign of Elizabeth, and of James the First, was the seat of Reginald Mohun, Esq. a younger brother to Sir William Mohun, of Hall, and a captain under Sir Walter Raleigh. This gentleman never marrying, sold the barton (which is held from the manor of East Greenwich, in Kent, by the payment of three peppercorns yearly when demanded,) with the royalty of wreck, and in November 1619, the 19th year of James the First, to Nicholas Kempe, Gent, who was the younger brother of Humphrey Kempe, of Lavethan, in Blisland, Esq. who is the chief of that name in Cornwall. ³
