[3] Pentecost Dodderidge was the brother and heir of Sir John I Doddridge (1555–1628), a Justice of the King's Bench, who had purchased for his seat the estate of Bremridge, near South Molton, Devon.

He became a bencher of his Inn in 1658 and published The Opinions of Sundry Antiquaries ... Touching the Antiquity, Power, Order, State, Manner, Persons and Proceedings of the High-Court of Parliament in England.

A special building was erected to house the books at the north-east corner of the chancel of St Peter's Church, Barnstaple.

The Dodderidge collection was removed to the North Devon Athaneum in 1888 and from there in 1957 on permanent loan to Exeter University Library.

[10] As his only son predeceased him, his heirs were his two sisters, one of whom was Dorcas Doddridge, the wife of John Lovering (died 1675) "The Elder", of Weare Giffard, a merchant based at Barnstaple[12] who served as one of his executors.

[14] John Dodderidge's will, dated 20 January 1658 and proved 20 June 1659, may be summarised thus:[15] A monument exists in Cheshunt Church, Hertfordshire, inscribed as follows: "To the memory of Martha Doddridge, wife of John Doddridge, of Branbridge, in the county of Devon, Esq., youngest daughter of Sir Thomas Dacres, of Hertford, Knt., who died in 1655.
