Stafford appears to have hailed from the city of York. Through most of his career he is distinguished in the city records (and sometimes elsewhere) by the epithet ‘junior’ from an older John.
This is not, of course, to say that Stafford did not have local clients before the early 1440s. From at least 1431 he was retained by Durham priory at an annual fee of 20s., a fee he enjoyed for the rest of his life; by February 1433, he enjoyed the same fee from the corporation of York, which he continued to serve until at least 1450; and in 1438 he offered mainprise on behalf of the priory of Newburgh in the North Riding.
None the less, only from the late 1430s did Stafford begin to play a part in local administration. In November 1439 he was appointed to his first ad hoc commission of local government, and four years later he was added to the quorum of the peace in the West Riding. In the meantime, on 3 Apr. 1443 Robert Neville, bishop of Durham, had named him his attorney in the courts of the bishopric at an annual fee of five marks, another indication perhaps that Stafford now spent much more of his time in the north than in London.
Stafford continued to play a part in the government of the West Riding into the 1450s, retaining his place on the quorum of the peace and appearing on the important commission for the assessment of the 1450 subsidy. But his successful, if unspectacular, legal career was approaching an end. His will, drawn up at York on 5 May 1458, demonstrates the wealth that this career had brought him.
