Rudy is one of those names that has been consistently in the US Top 1000 since the early 20th century without ever becoming overwhelmingly popular. It peaked back in the 1930s, when it briefly entered the Top 250, though more recent years have seen it make the latter end of the charts. Certainly more stylish than its parent name, Rudolph, which has been relegated to reindeers in English speaking countries, Rudy was given to 300 boys in a recent year.

Rupert is a charming-yet-manly name long more popular in Britain (where it's attached to a beloved cartoon bear) than in the U.S. Yet we can see Rupert as a more stylish, modern way to honor an ancestral Robert.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.

Prudence, like Hope and Faith, is a Puritan virtue name with a quiet charm and sensitivity that is slowly returning to favor, though it hasn't yet registered on the charts.

A name with a sound that is both unique and familiar, Beulah is a Biblical name, reminiscent of Bella, Luna, and Selah. In the Bible, Beulah is a place, applied to the land of Israel by the prophet Isaiah. Its meaning, "married", comes from the idea that the Israelites would "marry" the land, though other sources interpret it as meaning "inhabit".

Once upon a time, in the 1930s, Huey (yes, just Huey) was a Top 250 name. Could the 100-Year Rule bring it back?
