As the son of a distinguished local administrator and landowner, this MP inherited an influential place in county society, and his election as a shire knight in 1395 undoubtedly owed much to his father’s posthumous reputation. Robert Loxley the elder represented Surrey in at least six Parliaments, as well as discharging the duties of sheriff, escheator, j.p. and royal commissioner at various times during the course of his long career. Together with his wife, Margaret, who was herself the heiress to holdings in Southwark and Rotherhithe, he acquired land in the Surrey villages of Polstead and Compton, and at the time of his death, in 1390, he held other unspecified property in Sussex.
Unlike his father, Loxley showed scant interest in public affairs, and very little evidence has survived to illuminate his career. In October 1387 he and William Weston I acted as mainpernors in Chancery for John Hathersham I; and in April 1391 he witnessed a conveyance of property made by Elizabeth, Lady Grey of Stoke Dabernon, to John of Gaunt and others. He again appeared as a witness in June 1395, this time in London, although the deed itself concerned land in Surrey. No more is heard of him after that date, and, as we have already seen, he must have died well before 1410, by which time his son and heir, William, had settled his inheritance on trustees. Agnes Loxley probably outlived her husband for some years, since on her death her own property in Artington descended to Robert Danhurst (d.1418), the grandson of her first marriage.
