Scottish surnames were added onto the name of person, in order to distinguish them from others who bore the same name. Bynames were particularly prevalent in fishing communities in the northeastern part of Scotland, but were also used in the Borders and the West Highlands. In some cases within fishing communities, the names of fishing boats were tacked onto the names people in order to differentiate them from others. Examples of Scottish surnames derived from nicknames are: "Little"; "White"; and "Meikle" (which means "big"). One of the most common Scottish surnames is "Campbell", which is derived from the Gaelic "Caimbeul", meaning "crooked-mouthed"..
