Riley -- one of the most popular unisex names -- is trendier now for girls though for boys it's a classic, ALWAYS ranking in the US Top 1000.

We've seen Ray regain his cool, but could this country/cowboy name epitomized by Roy Rogers (born Leonard Slye), Acuff, and Clark, do the same?

A top ranking choice in England and Wales, making frequent appearances on the Telegraph Announcments, Rafe feels equal parts rugged, amiable, and posh. Traditionally seen used a variant of Ralph (itself from the Old Norse Ráðúlfr), it came into use in the 17th century to reflect this particular pronunciation.

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

Simple, short, and cool, Ray gives off retro vibes thanks to its 20th century popularity, and its links to jazzy Ray Charles and Ray-Ban sunglasses. A popular middle name for boys, it is well established as a given name too.

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.

Roland is a chivalrous old name made famous by the supposedly eight-foot-tall romantic hero and nephew of Charlemagne, celebrated in medieval poetry and song. It is more widely heard in the US now in its Spanish form, Rolando. You might want to consider rollicking short form Rollo, either on its own or as an abbreviation of Roland. Orlando is the graceful Italian form.

Raphael is a romantic archangel name that sounds both artistic and powerful. Raphael is also a great cross-cultural choice, with significance for people with both Latinate and Jewish roots, plus plenty of grounding in the English-speaking world.

Reuben is derived from the Hebrew words ra’a, meaning "to see, to understand," and ben, "son." As a phrase it translates to "behold, a son." In the Bible, Reuben is Jacob's first-born son by Leah and the founder of one of the tribes of Israel.

In the World War II era, Roger had nothing but the most positive associations, actually used by military personnel to mean 'Received and understood'--or A-OK, and though it is now on extended furlough, it does have a long and distinguished history.

This sleek, warm-hued spelling spin on Rowan was chosen by Sharon Stone for one of her three sons back in the 2000s and it has since risen in popularity in the US. While it remains a long way behind its sometimes sound-alike Rowan, it was still given to more than 140 babies in a recent year.

A classic old Norman name popular for a thousand years and favored for kings (Richard Nixon was named for Richard the Lionhearted), as well as the hoi polloi (as in every Tom, Dick and Harry), Richard was the sixth most popular US boys’ name in 1925, and was still Number 8 in 1950, but is now much less popular.
