succeded his father (or brother?), Thomas Luttrell to the estate
at East Quantockshead
". . .was created one of the original Knights of the Bath* when that illustrious Order was established by Henry IV, two days before his coronation in 1399. Five months later, the same king assigned to his 'beloved and faithful knight,' Sir John Luttrell, whom he had attached to his own person, an annuity of forty pounds for life from the revenue of the county of Somerset. Sir John Luttrell was Sheriff of Dorset and Somerset in 1400. In the month of May, 1403, he took up arms in the king's behalf, 'to resist the malice of a certain Henry Percehay, Knight,' and, when on the point of starting, made a will by which he directed that if he should die without issue before returning to his mansion at East Quantockshead, his estates should pass to his 'cousin,' Sir Hugh Luttrell. The event showed that he acted wisely in making his will, for he died within the next few weeks. In him the direct line of the Luttrells of East Quantockshead came to an end."
