“ID: I17951
Name: *Reginald DE DUNSTANVILLE
Sex: M
Name: Reginald FITZROY
Birth: ABT 1110 in Dunstanville, Kent, England 1
Death: 1 JUL 1175 in Chertsey, Surrey, England 1
Occupation: 1st Earl of Cornwall 1
Occupation: Sheriff of Devon 1
Note:
His mother was Sibyl Corbet, the wife of Herbert Fitz Herbert.
He was an illegitimate son of Henry I of England and Lady Sybilla Corbet.
Reginald had been invested with the Earldom of Cornwall by King Stephen of England, but having afterwards taken up the cause of the Empress Matilda, his sister, he forfeited his lands and honours. Possibly during 1173 he grants a charter to his free bugesses of Triueru, and he addresses his meetings at Truro to All men both Cornish and English suggesting a continuing differentiation.
Also he had illegitimate children:
Henry FitzCount, Sheriff of Cornwall, Earl of Cornwall (d. 1222).
William FitzCount.
