The Edgcumbes originated in Devon, but acquired the Cornish seat of Cotehele, Calstock in the fourteenth century. Henry VII rewarded their loyal service with substantial estates confiscated from the Bodrugan family in Cornwall, together with the honour of Totnes, Devon. In the next generation they acquired by marriage additional property west of Plymouth where they built Mount Edgcumbe. Financial difficulties forced the sale of the Totnes lands in the mid-sixteenth century, but the family continued to qualify for local office in Devon as well as in Cornwall on the strength of Mount Edgcumbe’s location just inside the Devon border.
Peter’s attempts to establish himself as a mining speculator, including investment in the Mines Royal Company, worsened the family’s financial position, and by 1602 they were more than £4,400 in debt. To resolve this crisis, Edgcumbe married Anne Carey, no beauty but ‘a very good housewife, and very wary in her expenses’, according to her sister-in-law. Anne brought with her a £2,000 dowry, subsequently increased by £500 in lieu of a legacy. At the same time Peter’s estates were put into trust for six years with the object of clearing the remaining debts, though Edgcumbe was provided with the use of Cotehele.
In 1614 Edgcumbe was again returned to Parliament, after an absence of 21 years. His motive for standing has not been determined, but he may have been seeking to boost his profile in Cornwall. His means of obtaining a seat at Bodmin is likewise uncertain, though his brother-in-law Edmund Prideaux’s ownership of the rectory may have influenced the electors.
In early 1616 a rumour of a new Parliament reached Cornwall, and Edgcumbe wrote to Totnes on 5 Feb., requesting one of the borough’s seats for himself or his nominee, should an election be called.
In the following year Edgcumbe again entered Parliament, this time resuming his former place at Grampound, but was named to only one legislative committee, concerned with a long-running dispute over control of the West Country fish-processing industry (4 May).
In 1626 Edgcumbe was removed from the Devon bench, apparently because of the smallness of his estates rather than for any other reason, but he was restored after three years.
The factional ill-feeling of the late 1620s took several years to die down. Edgcumbe dragged Eliot through the courts over at least two petty disputes while the latter was confined to the Tower.
