I bought a little copy of Alumni Felstedienses today which lists the names of boys who entered the Felsted school from its foundation to 1903. The first headmaster was at the school in 1566, but the names of the pupils don't start until the 5th headmaster is at the school 1627 - 49. The biographical detail relating to each boy varies, but often includes year of birth and death, name of father and subsequent employment. Some C19th entries include address, clubs, sports played and subsequent university. There is an index and I would be happy to 'lookup' any names.
