Mason’s father was a Kent yeoman, who bequeathed his son £100 and left instructions for him to be brought up ‘in learning’.
Mason drew up his will on 20 June 1625, in good health but conscious that ‘the care of a man’s debts is a thing of principal regard’.
In a codicil to his will on 10 July 1626, Mason left to his eldest son William a half-share in his office, his chamber in Gray’s Inn, his law books and his gown, all of which he hoped might suffice to raise portions of £200 apiece for his younger sons. He also bequeathed a ring to Heath, asking him to be ‘loving and kind to my children’. His date of death is unknown, but it must have taken place by 2 Nov. 1628, when his widow sold Barningham to Maurice Barrowe†. His will was proved the following April.
