... [PCC 45 Welles; C142/120/12.] St. John made his will on 6 Apr. 1558. After commending his soul to God, he appointed as executors his second wife Anne, his sons Oliver and John, and a son-in-law Edmund Elmes, and as overseers his son-in-law Bedford, Henry 11th Lord Morley and John Zouche, the last perhaps the knight of the shire for Derbyshire at the time. From the profits of his manors of Fonmon and Penmark, spread over a period of 12 years, the executors were to pay sums of money totalling £372 to his children and grandchildren, to provide rings for his daughters, to give £27 to the parishes within two miles of Bletsoe and to give what was left over from £480 to his heir Oliver St. John. Two of his daughters were to receive goods and money worth altogether 400 marks, his son John was to have his gold chain, and his plate was to be shared equally between Anne and Oliver. St. John died on 19 Dec. 1558 and the will was proved on 27 Feb. 1559. The annual value of all his Bedfordshire property, excluding that settled on Oliver in 1543, was reckoned in his inquisition to be £226.
