Favorite Names April 2015 (Boys)

The friendly and sporty feeling Nolan blends some of the best qualities of other popular boy names. With the gentle but energetic sounds of Noah, a hint of the classic Nicholas, and the cool, surname-style vibe of Greyson or Colton, it makes for a familiar and grounded choice.

Oliver is an international star, ranking near the top of the charts in the US and throughout the English-speaking world, along with a host of European and Latin American countries, from Norway to Chile, Slovenia to Switzerland.

River shares the tranquil feeling of all the water names, and seems to have pretty much escaped its past strong association with River Phoenix and his unfortunate fate. Actor Joaquin Phoenix named his son with actress Rooney Mara after his brother River.

With its gentle sounds and earthy vibes, the name Rowan feels like a fusion of different styles. A word name, a surname, and a gender-neutral name, Rowan is rustic but trendy, blending the vibes of both Owen and Oakley.

See the popularity graph below for the name Theo? It's been heading straight uphill since 2010, when it hopped back onto the Top 1000 after a 60+ year absence.
