Thomas Murfyn (or Mirfyn, Merfyn, Murphin), (died 1523) was a Sheriff and Lord Mayor of London. Biography Thomas Murfyn was a native of Ely, Cambridgeshire, and son of George Murfyn. He was a member of the Worshipful Company of Skinners in the City of London, who served as Sheriff of London from 1511 to 1512, and as Lord Mayor of London from 1518 to 1519. Mark Noble claimed that Murfyn was probably not knighted until after his election to the mayoralty. Although Murfyn is often referred to in later documents as Sir Thomas Murfyn, there appears to be no record of his knighthood. It became common practice after Thomas Muryfn's mayoralty for Lord Mayors of London to be knighted and this may be one reason why later documents refer to him as "Sir". The misunderstanding may also be due to the translation of the form of address "Dominus" (a term of courtesy used in reference to an official) as "Sir". In his will, which was made on 2 September 1523 and proved in London on 15 October 1523, Murfyn refers to himself as "Thomas Mirfyn citizein and Alderman of the citie of London". The memorial to the graves lost in the Great Fire of London at St Paul's Cathedral, which lists "Sir Thomas Miryfn", may be perpetuating this error rather than evidence of a knighthood. Family Thomas married firstly, Alice Marshall, by whom he had thirteen children: Thomas John George, who became a monk Thomas John Frances Richard John Robert Edward (d. 1528), a wealthy London merchant who married Alice (d. 1560), widow of John Brigandine of Southampton, and daughter of Oliver Squier of Southby, Hampshire, by whom there were no surviving children.

By Elizabeth, he had a daughter: Frances (c.1520/1–c.1543), who married Thomas Cromwell's nephew, Sir Richard Cromwell by 8 March 1534.
