Perhaps descended from the John Everard who held land at Stratford-sub-Castle, on the outskirts of Salisbury, in the 14th century,
In 1421 Everard was elected in Salisbury to the city council of 24, and two years later he was present at the Salisbury elections to the Parliament to which he was himself returned for Old Sarum. It was probably he who, in 1427, went surety for the parliamentary attendance of Richard Baker, burgess-elect for Cricklade, and who was present at the Wiltshire elections of 1429. Five years later he was among the county gentry considered important enough to take the general oath not to maintain those who broke the peace. Everard is recorded as attending meetings of the convocation of the city of Salisbury in 1429, 1434 and 1440 (in which last year he was serving as bailiff); and he contributed 6s.8d. towards the fee farm of the city in 1441-2 and twice that amount two years later. Since he is not mentioned in the Salisbury records after 1444, it is possible that he was the verderer of Clarendon forest who died in February 1445.
