Robert "died during his term as sheriff on 12 Aug. 1420, at the early age of 36. His heir was his elder son, Thomas, then aged ten, who subsequently sat for Shropshire in 1435 but died less than four years afterwards when, on the death of Robert's widow (who had meanwhile married Sir William Mallory of Papworth, Cambridgeshire), the family estates passed to Robert's younger son, Roger Corbet."
