Evans : Ifans / Ifan. A very popular Welsh surname ultimately derived from John via Ieuan. Fairly recently Ieuan developed into Evan, Ifan and Iefan. In modern times the spelling Ifans has been taken on by some.
Famous people with the Welsh surname Evans include:
Lyn Evans - Project leader of the controversial large Hadron Collider project in Cern Switzerland.
David Howell Evans - Also known as 'The Edge' from the band U 2'.
Gwynfor Evans - Famous Welsh politician and thinker who went on hunger strike to demand a Welsh language channel and led in making Plaid Cymru / The Party of Wales a popular party in Wales.
Oliver Evans - A prolific Welsh American inventor. His most important invention was an automated grist mill which operated continuously through the use of bulk material handling devices including bucket elevators, conveyor belts and Archimedean screws. He also produced an improved high pressure steam engine and developed the idea of applying the steam power to wagons. He therefore lays claim to inventing the first self powered land vehicle in the United States as well the first self powered amphibious vehicle and dredger. As Evans also designed a refrigeration machine which ran on vapour in 1805, he is often called the inventor of the refrigerator, although he never built one (his design was modified by Jacob Perkins, who obtained the first patent for a refrigerating machine in 1834).
Rhys Ifans - Actor made famous in the film 'Notting Hill'.
