Members of the Bache family descended from Genoa, before setting up as merchants in London’s Lombard Street. For several decades two dealers, both named Antonio Bache (presumably father and son), supplied the Royal household with spices and luxuries. They also loaned substantial sums of money to the Crown. They were amongst a number of Lombard and Tuscan merchants who left the country after Edward III repudiated his enormous debts to foreign bankers in 1345. It is not known how Thomas Bache relates to Antonio. The former entered the Church and served as a Crown official in England, before moving to Ireland in the late 1360s where he served as Chancellor of the Exchequer in 1376, and Lord Treasurer 1400/02. He died around 1410.
