Olivia, a lovely Shakespearean name with an admirable balance of strength and femininity, is the Number 1 name for baby girls in the US and one of the top girls' names around the world.

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.

This name, like Omar and Amari, has been in the US Top 1000 for many years. After taking a downturn in 2008, it's now again on the upswing. Actor Omari Hardwick keeps it in the public eye.

More and more frequently heard as the Gallic version of Oliver, Olivier could be seen as a tribute to the great British actor, Sir Laurence O.

What is so rare as a month named June? October – and November and December – are a lot rarer. Brisk and substantial, they're so much more memorable and modern than April or May. October got its name via being the eighth month in the old Roman calendar. Some related, more feminine variations are Octavia and Ottavia.

Another increasingly popular member of the Omar family, this one perhaps influenced by hip-hopper Omarion Granberrg (born Omari) of the group B2K.
