The Surname of Vincent is first documented in the "doomsday book." The book was a collection of the names and land owned in britain from 1066 to 1086 when the book was finally finished. The book was an order of King William a "Norman", who conquered britain from the newly deemed land of Normandy in what is northern france today. The Normans brought the name with them from the netherlands and surround areas as the normans were vikings who by peace agreement with france took control northern france deemed Normandy.
The Norman or Viking Language was old frankish, which even farther back was what is called Proto-Germanic. This proto-germanic which is believed to have existed sometime after 1500bc was spoken by the earlist germanic tribes of northern europe and the netherlands. The Mixing of The Proto-Germanic and Latin when the Southern Europeans invaded in as early as the 3rd century is believe to be where VINCENT could have first been seen. The Latin "Vincere", meaning To Conquer could have been the conceptiong point for the surname when mixed with the Proto-Germanic. This places the original conception of the Vincent surname sometime between 200AD and 900AD. Which it would to have happened from when the early germans fought the southern europeans all the way to when the vikings expanded to northern france.
