He was for a time Vicar at St 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.

The link between the Cornish language and Catholicism was also exhibited in the activities of Kennall, at St Columb, where he was still holding Mass as late as 1590.
