This is not a girl's name! It's short for Fergus, which is a boy's name. People only associate it with girls because of Fergie (Stacie Ferguson) from the stupid Black Eyed Peas!
I definitely like this name. But I don't really like it as a girls' name, and I am not a fan of Fergie from the Black Eyed Peas. Because he would be associated with her, I would not name a son Fergie.
This is an okay nickname for someone by the last name of Ferguson, but horrible as the official first name of a person. The nickname sounds feminine to me, and there's no doubt Sarah Ferguson and the singer Fergie are reasons why I can't picture the nickname on males quite as easily, but it is imaginable. As a first name, the name sounds very immature and unserious, and it doesn't have a lot of class and dignity to it. Besides, the singer has ruined the name for many people.
Oh God, no! The name Fergus sounds too masculine to be adapted to a feminine name and this name is proof of that; it grates on my ears and it also sounds too infantile to be used as a given name.
It sounds really nicknamey, and plus it's attached to two famous people. Sarah Ferguson is a rather unfortunate namesake. The American singer Fergie is a much better association, though, and I do like her music, so I'd prefer to think of her when I hear this name.
