Damiet was probably a native of Dartmouth. By marrying the widow of William Henry, the parliamentary burgess of 1381 and a kinsman of the mayor of 1389-90 (when Damiet himself was bailiff), he acquired an interest for life in property in the town and on the other side of the estuary at Kingswear.
Damiet’s last term as a customer, which began in 1404, centred on Melcombe Regis in Dorset, and it was there that he settled during his later years. In 1408 he leased out his house and garden on the sea-front at Dartmouth to his stepson, William Henry, for the term of his own life, and in the following year, now described as dwelling at Melcombe, he made a formal release to Henry of his interest in the property.
