In 1468, while assisting at Mass at the church of the White Friars in London, he was called out to the porch of the church and stabbed to death by John Herthill in a dispute over a mortgage; when offered payment earlier by Herthill, Brome had kept the land. In 1471 Nicholas Brome avenged his father by killing Herthill, for which crime he was ordered to find a priest to say mass daily for twoyears in the church of Baddesley Clinton for the souls of both victims, and topay to the widow Elizabeth Herthill 33s. 4d. John Brome's father, John Senior, was a burgess of Warwick in 1407, and married Joan, daughter of Thomas Rodie of Baddesley.
