The original personal name is Greek, meaning "people-victory" and has produced over one hundred alternative and variant derivatives. In this case the medieval development was, Nicholas - Nichol - Col - Cols (son of Col) - Collins or Collis(s), (son of Col) and shows how the medival personal names were a very fruitful source of modern day surnames.
