His profession was a dealer in fine cloth, in addition to being a moneylender.

[1][2] John Roysse signed an indenture, consisting of 31 ordinances, on 31 January 1563, which essentially financed the building of a new schoolroom.

Roysse was aged 63 in 1563 so he wanted the schoolroom to measure 15 feet in width and 63 feet in length, in addition to having 63 free scholars.

The schoolroom was constructed on the south side of the gateway of the former Abingdon Abbey, on Bridge Street.
