William’s brother, John, abbot of Tavistock from 1402 until his death in 1422, made his mark as a monastic administrator and set about the reconstruction of the conventual church. William himself was often employed on the affairs of the abbey: in June 1417, when Roger Oskeriswill, one of its tenants, died leaving a three-year-old daughter as his heir, it was he who went to Exeter with the steward, Thomas Raymond, to claim the child as the abbot’s ward; and he also acted on his brother’s behalf as an attorney at the assizes at Exeter.
From 1407 onwards May acted as a feoffee of the property of his ‘cosyn’ Ranulph Hunt, and later served as executor of his will. This involved him, some time between 1413 and 1417, in a suit in Chancery against Austin Strode, clerk, over chattels of Hunt’s worth 100 marks which, along with the will and various muniments, he had left in Strode’s keeping while he was ‘hors du pays’, but which the clerk refused to hand over when he returned.
