Being both Scottish and Cameron, I thought I would add a little comment.Cameron is not a unisex name. It is in fact (in Scotland) a very popular Scottish boys name. In 2007, it was the 6th most popular name for newborn boys (you can search for Scottish births and registrars for the rest), which was the same position it held the year before. The years before that I think it was even more popular. For example, in my son's class there are three boys called Cameron. At the same time, not one girl in Scotland was, or probably ever will be registered Cameron, simply because it is a boys name.I realise that in America, it may be considered unisex, although comments below suggest that came from one famous actress being given the name, but should she ever come to scotland, she would be a girl with a boys name.
