Berkeley was a
Justice of the Peace for Leicestershire from 1442 to 1458, and
Sheriff of Rutland between 1443 and 1444. In December 1457, Berkeley was appointed as one of Leicestershire's Commissioners of Array. The commissioners raised 226 archers to help repel
Richard, Duke of York's
Yorkist rebellion and again in 1459. The Marmion estate was composed of over 2,500 acres spread over several counties. As well as being an attractive prize, it was owned by way of a complex set of homages and services to multiple overlords. In 1468, Berkeley accused William Purley of entering his land two years earlier and stealing 20 hares, 200 rabbits, 12 pheasants and 20 partridges using swords, bows, and arrows. Purley was either found not guilty or let off for some reason as he appears to have later married Berkeley's daughter Joyce. Berkeley was appointed as Sheriff of Rutland in 1471 and as a Justice of the Peace for Rutland in 1470–1475. Berkeley served in
Parliament for Leicestershire between 1472 and 1475. Berkeley died in 1488. He is buried in an
alabaster topped altar
tomb with his wife Petronella in St Peter's Church, Wymondham. ==Family==
