The name Rushbury is thought to derive from Rush Manor[REF], but other evidence suggests that it could originate from the Old English 'risc', literally meaning 'a place where rushes grow', and the Old English word 'burh', meaning a 'fortified place'; putting the two together gives 'Rush Fortification' [REF].
According to the Domesday book Rushbury had the most arable land compared to the surrounding manors.
