A member of a prominant Leicester family, Roger was a brother of the mercer, William Humberston, MP in 1378 and mayor in 1389-90, and possibly an uncle of Ralph Brasier alias Humberston.
Humberston owned a considerable amount of property in the borough and suburbs, including a tenement, two messuages, six cottages and various plots of land. In December 1416 he was pardoned the forfeiture of his goods and chattels as a result of his outlawry in the court of husting in London at the suit of the executors of John More, mercer.
