Moyle’s origins are obscure, but it is tempting to speculate that like his namesake, the MP for Southwark, he was related to Walter Moyle*, the future judge, in whose private property transactions he occasionally played a part.
Although much of Moyle’s later career was to be focused on the south-east, he appears to have found his earliest clients further afield. In the summer of 1434 he was acting for the under-age earl of Devon, Thomas Courtenay, in the court of common pleas,
In parallel with Moyle’s growing importance among the fellowship of Lincoln’s Inn, his private practice burgeoned. He acted as counsel for a wide range of suitors in the court of Chancery;
By the early 1440s Moyle was evidently sufficiently established in the city of London to be able to contract a mariage to Margaret, the daughter of the draper Thomas Eyre. While she was not an heiress, she may have brought her husband a dowry in cash, for in March 1442 he settled upon her a jointure in property in Greenwich Lane in the parish of All Hallows the Great.
Moyle made a will on 16 Apr. 1453 in which he arranged for the disposal of lands and tenements in both London and Kent. These were to be conveyed to his widow Margaret, with reversion to their son, John, and with further remainder to Thomas Eyre, Margaret’s brother. The will was proved on 25 Nov. following, and in February 1454 Moyle’s executor John Bekyngham and the other feoffees, transferred the property in London to Margaret.
