Surname or Lastname
English
English : ethnic name for someone from Flanders. In the Middle Ages there was considerable commercial intercourse between England and the Netherlands, particularly in the wool trade, and many Flemish weavers and dyers settled in England. The word reflects a Norman French form of Old French flamenc, from the stem flam- + the Germanic suffix -ing. The surname is also common in south and east Scotland and in Ireland, where it is sometimes found in the Gaelicized form Pléimeann.German : variant of Flemming, cognate with 1.
