Sorry, buts it s pretty awful for a girl. It is a distinctly male name. Wouldn’t use Reagan for a girl any more than I would use Megan for a boy.
Megan is a well used girls name. Reagan is not a male first name. It fits my daughter perfectly and now everytime she hears Ronald Reagan’s name on the tube she gets excited. If I wanted to name my son after Reagan I would name him Ronald, but aside from Ron himself I dont particularly like that name.
