Origen: Escocés. The ancient Scottish name McGaffin and Gaffan is carried by the descendents of the Pictish people. It was a name for a metalworker. The Gaelic form of the name is Mac Ghobhainn, which means son of the smith. First found in Inverness-shire, where they were seated from very ancient times, some say well before the Norman Conquest and the arrival of Duke William at Hastings in 1066 A.D.
