Finest of all are the famous Paston Letters, written by and to a family of Norfolk gentlefolk, and crammed with information about high politics and daily life.[6] Less interesting, but valuable all the same, are the letters of the Plumptons, who were lords in Yorkshire.[7] But for our purposes the most interesting are two other collections, to wit, the correspondence of the Stonors, whose estates lay chiefly in Oxfordshire and the neighbouring counties; and the Cely papers, kept by a family of Merchants of the Staple.
These two collections give us a vivid picture of wool staplers in their public and private lives.

The Cely papers cover the years 1475 to 1488, and it so happens that during that period William Stonor (he became Sir William in 1478) also became interested in the wool trade, for in 1475 he married Elizabeth Riche, the daughter and widow of wealthy city merchants.

The Stonors had great sheep runs on their estates in the Chilterns and Cotswolds, and William readily perceived the advantage of his alliance with Elizabeth's family, who were interested in the wool trade.

Consequently he entered into a partnership with a friend of his wife's, a Merchant of the Staple in Calais, named Thomas Betson, who is the subject of this study, and until Elizabeth's death in 1479, he took an active part in the export trade.

Thomas Betson died in 1486, and was thus an exact contemporary of those other Merchants of the Staple, George and Richard Cely, whom he must have known; indeed, William Cely, their cousin and agent, writes from London to George in Calais in 1481, advising him that he has dispatched 464 fells to him in the _Thomas_ of Newhithe, 'and the sayd felles lyeth nexte be afte the maste lowest under the felles of Thomas Bettson'.[8] By the aid of the 'Stonor Letters and Papers', which contain many letters from and concerning him during the years of his partnership with Sir William, and of the 'Cely Papers', which are full of information about the life of a Merchant of the Staple at Calais, Thomas Betson may be summoned before us by a kindly magic until he almost lives again.
