Some parents are choosing this popular boys name for their daughters (in the US there were well over 100 female Ryders born last year). Is it the connection to Winona that makes this feel somewhat more feminine than some other boys’ names?

Ruadhan (sometimes spelt with a fada: Ruadhán) is a fashionable name in its native Ireland. Borne one of the Twelve Irish Apostles, it originated as a diminutive of Ruadh, meaning "red-haired". It has sometimes been Anglicized as Rowan.

Rock definitely has a macho image, if a somewhat caricatured one, ala The Rock. But with the rise of word names and also of tough guy names, Rock feels more plausible than it did a generation ago.

Starbaby name that might prove too supercharged for real life, but if like director Robert Rodriguez you're interested only in boys' names starting with R, you may need to add Rocket (and Rebel and Racer) to your list.

More authentic and original form of Ryan, but far less common of the two spellings in the US. There were about 170 baby boys named Rian in the US last year, versus over 4000 named Ryan.

A euphonious and lovely name with a dark-eyed, long-flowing-haired image, Raphaela is, like Gabriella and Isabella, beginning to be drawn into the American mainstream.

With its soft sounds, its unisex appeal, and its nature connection, Rowan has become a very popular name for both boys and girls, given to nearly four boys for every girl.

Riot has all the sounds of a trendy name — the first syllable that of trendy choices like Ryder, Ryker, and Rylan, rhyming with Wyatt.

Romer might be considered a streamlined spelling of the German surname Rohmer, whose root means fame or renown, or a name that was given to those who made pilgrimages to Rome, which is related to Romeo and its brothers.

Pretty and unusual, worth consideration.

For parents who hope their child will one day carve their own path.
