I thought it was also French. A Collier is a necklace in French and the spelling is French. Colyer in England is the English spelling. Would like to know if it indeed is French as well.
The surname COLLIER is found in the English counties of Surrey, Cheshire, Berkshire, and Staffordshire. By the time of the first census in America in 1790, many COLLIER families had settled in this country. The average COLLIER household had 5.5 members and census records indicate that many more COLLIER head-of-households living in Virginia, North Carolina, and Kentucky than in any other part of America. Official United States records compiled in 1974 indicate that in that year COLLIER was the 487th most frequently occurring surname in the nation. Today (1978) there are approximately 56,200 adult Americans named COLLIER
