[1][2] His nephew, John Fabyan, married Anne Waldegrave, by whom he had a daughter, Mary Fabian, wife of Sir Thomas Spert.
In 1495 he was elected Master of the Drapers, and in 1496 was chosen to petition Henry VII on behalf of the Company with respect to the levies on cloth exported from England to Flanders.
In 1503 he resigned his office of alderman on the ground that he lacked the financial resources to support election as Lord Mayor.
[2] A continuation in 1509 appears also to be attributable to Fabyan,[2] and includes events personally witnessed by him, such as the arrest in 1468 of Thomas Cooke,[4] a prominent merchant in London,[5] and the arrival in England in 1502 of three men, inhabitants of Newfoundland, 'whom the King kept a time after'.
[7][2] Fabyan was executor of the will of his father-in-law, and through his wife inherited a house called Halstedys together with other lands in Theydon Garnon, Essex.
In his will, proved 12 July 1513, he left bequests to his wife, his six surviving children, his cousin, Dorothy, and the mercer Robert Tate, Lord Mayor of London, among others.
[2] Ellis notes that a John Fabyan, in his will dated 16 March 1541, mentions 'the Lady Spert' (see above) as his sister, and refers to the Earl of Southampton as his master.
