Mysterious origins, slightly mysterious name. Aaron crept onto the charts in the early ’70s, going from number 106 (in ’67) to 52 (’70) in a matter of four years, and has hovered around the top 30 to top 50 names ever since. The meaning of the name is a little unclear, but Aaron’s biblical role is not -- he was the older brother and spokesperson for Moses. Since Aaron never became super-trendy or spiked very high in popularity, it doesn’t really have the opportunity to become untrendy. If you like the name, go for it -- it’s a good, solid choice.
