Richard Courtenay

Need proof for date of death. He couldn't have died before the birth of his own son.

"In the latter part of the fifteenth century , Sir Edmund Courtenay, second son of Sir Philip Courtenay of Powderham , by Elizabeth , daughter of Walter, Lord Hungerford, and brother of Courtenay, Bishop of Winchester, having married the heiress of that manor, settled at Deviock in the parish of St. Germans.

"His son , Richard , was of Lostwithiel, and left three sons.

" Lawrence, the eldest, was of Ethy in St.Winnow , which was sold by his descendant, Francis Courtenay , Esq., in 1634. We have not been able to trace when this branch became extinct,

"...nor that of Courtenay of Deviock, which was continued by William the second son.

" John Courtenay, the third son of Richard Courtenay of Lostwithiel, settled at Tremeer in Lanivet, married the heiress of Trengove, and was ancestor of the Courtenays of Tremeer and the Courtenays of Lanivet, both now extinct.

"The former [Courtenays of Tremeer] intermarried with Courtenay of Trethurse, and became possessed of that estate , as will be explained below."
