Capell’s earliest known ancestors were settled at Capel in Suffolk during the twelfth century, but the family’s fortunes were laid in the early Tudor period by Sir William Capell, a London Draper who served twice as lord mayor and represented London in Parliament three times. Sir William acquired a great estate in Essex and Hertfordshire, which eventually descended to Capell’s father. As a younger son Capell himself stood to inherit only an annuity worth £20,
Capell received a university education, acquiring a fellowship at Queens’ College, Cambridge and an MA. His marriage meant that he did not subsequently progress to an inn of court, leaving a gap in his education of which he was keenly aware for, as he later confessed, he was only ‘slenderly studied’ in the Common Law.
Despite his willingness to give way to Denny, Lord Rich remained nervous that Capell would harbour resentment against Barrington, who had deserted him in order to ensure his own election.
Capell’s legislative concerns embraced a variety of religious matters, such as church attendance (19 Mar. 1606), non-communication (7 Apr. 1606), the enforcement of the penal statutes (added 27 Mar. 1606), the restraint of ecclesiastical canons which had not been confirmed by Parliament (11 Dec. 1606), pluralism (4 Mar. 1607) and subscription (14 Mar. 1610).
Capell’s inclusion on the committee for the bill to assure various small plots of land to the 1st earl of Salisbury (Robert Cecil†) ‘for the more commodious use of his mansion house in the Strand’ (5 May 1606) could be interpreted as an expression of gratitude to Salisbury for agreeing not to prick him as sheriff of Essex in the previous November. It seems more likely, however, that it formed part of a general attempt to court Salisbury’s favour from at least April 1605, as he regularly plied Salisbury with gifts of game from his Essex estate.
Capell remained exercised by the inadequate state of his finances for the rest of his life. In his will, drawn up six months before his death, he asked to be buried without pomp ‘because I know the mediocrity of my estate and livelihood cannot well sustain the charge of such rites and exequies as are many time unnecessarily bestowed upon the funerals of men of like sort and degree without some hindrance to my poor children’. Nevertheless, he was far from penurious, assigning a total of £2,000 to his three daughters for their dowries and £500 each to three of his younger sons. No mention was made in the will of his eldest son and heir, Gamaliel, who eventually inherited all his father’s property, including the two Essex manors assigned to his mother (Capell’s sole executrix) for her lifetime.
