Career
Kennall was Canon of 8th preb., Christ Church, Oxford, from 1559–1592, Archdeacon of Oxford, Oxford, from 1561–1592, Canon of 6th preb., Rochester, from 1556–1559, and Archdeacon of Rochester, 1554–1560. He was for a time Vicar at Street Columb Major in Cornwall and had a strong interest in the use of the Cornish language. Carew, who published his survey of Cornwall in 1602, notices the almost total extirpation of the Cornish language in his days.
He says: The principal love and knowledge of this language liveth in Doctor Kennall, the civilian, and with him lieth buried.
