The Edgecombes were an ancient south-western family that took its name from a manor in the Devon parish of Milton Abbot. In the late fourteenth century an earlier William Edgecombe, a probable ancestor of the MP, acquired the Cornish manor of Cotehele, which became the family seat, by his marriage to its heiress.
Since it seems possible that there were, in fact, three Williams in succession, it is impossible to be certain whether it was the MP who in 1405 received a settlement of lands in Lovehille in Calstock at an annual rent of 6s. 8d. from William Lovehill.
There is no suggestion that Edgecombe either engaged in trade or practiced the law, and it seems that his income derived principally from his property. As he was a younger son, this must have consisted chiefly of the holdings he had acquired by marriage.
It is possible, albeit not certain, that at the time of his election Edgecombe was already embroiled in an acrimonious quarrel with the wealthy Roger Champernowne*, who accused him of forging property deeds in an attempt to deprive him of some of his estates at Bere Ferrers. Litigation over the issue continued in the court of common pleas until at least the autumn of 1457, but it is unknown whether the matter was ever settled.
