Alois and Aloysius are variation of Louis. Alois ranked in the US Top 1000 until the 1930s, and still ranks in the Top 1000 in Germany. Last year in the US, only seven baby boys were named Alois.

The name August is at its highest point since the 1890s, when it ranked among the Top 100 boy names in the US. And deservedly so, given its great meaning, historic roots, and cool nicknames.

More likely to be spelled Constantine, this was the name of the first Christian emperor of the Roman empire, as well as three Scottish kings. Previously thought of as too bulky and unwieldy a name for a modern child, these days it would be perfectly acceptable.

The traditional German spelling of this name, used by Goethe, Bach and many other luminaries.

Joseph is one of the most classic names in American nomenclature, popular with parents from many ethnic backgrounds and having dual-religious appeal.

Manly almost to the point of macho.

This name once seemed a bit grand and pompous for an American baby boy, but a significant number of parents are now preferring it as a substantial platform for the nickname Max, among them Jennifer Lopez and Marc Anthony, who chose it for their twin son.

You've got the red-nosed reindeer to transcend, but there are other distinguished personages named Rudolph, Rudolf, and Rudy.
