BASKERVILLE FAMILY HISTORY
Supplied by Brian Erwin
Edited by Peter Baskerville Rance.
Sir John Baskervilles second son, John, married Eleanor, heiress of Thomas Helcott of Wotton, of whichplace he became possessed in the right of his wife, and their son William, hadthree daughters, one of whom married Thomas Pembridge of Mancel Gamage. Sir John's only daughter, SIBELLA, was wife to RICHARD ROWDON. He died in 1455 and was succeeded by his eldest son James Baskerville, who was made knight banneret on the Battlefield of Stoke and Knight of the Bath at the Coronation of Henry II. His wife Sybella or Katherine, Devereaux, was daughter of lord Farrers of Chartley. Through this alliance the Baskerville family derived the royal blood of the Plantagenets, along with that of Castile and Leon. This couple's third son was Philip who married the widow of John Scudmore and he had a son Thomas of Netherwood, in the parish of Thornbury. [1990 P.B.R. My research shows that it isfrom this Thomas that my own branch of the Baskervilles is descended (See recently published copy of our Family tree)]
