Stacy, who came from Leicestershire, shared with his mother from 1387 a corrody in Leicester abbey, which the King ordered the abbot to award them for the rest of their lives, for what reason is not revealed. He settled in Nottingham shortly afterwards, and in 1390 acquired tenements in the weekday market and a messuage in The Poultry. In 1395 he was accused in the local courts of blocking a ditch with timber. His later purchases included a dwelling in Hounds Gate, a messuage in the Saturday market and land on West Rye Hill.
Stacy himself produced woollen cloth, and consequently during his term as alnager his wife, Maud, was assessed for payment of the subsidies on 44 ‘dozens’ in his stead. But after he handed over the seals of office to John Bothall, in 1403, he once again re-assumed direct responsibility for the charge.
Stacy is last heard of in April 1419, when he placed nine messuages in the hands of trustees. Some time after 1432 his widow brought a suit in Chancery against the surviving executor of his will for failing to complete a sale of the reversion of property in accordance with his last wishes. In 1442 she transferred to her sister Margaret, widow of John Bingham, all her share of their late father’s lands at Wilford.
