Spencer is a name that has everything: it's both distinguished sounding and accessible, dignified but Spencer Tracy-like friendly. Picked by several celebrities (a couple of times even for a girl), adding up to an enthusiastically recommended choice.

Kevin came to the US with the large wave of Irish Immigrants after World War I, hitting the US Top 1000 list for the first time in 1921 and never leaving.

Sean, after a long reign as one of the top Irish boys' names in the US, has now slipped as parents look to fresher Irish choices such as Liam and Aidan. In Ireland, Sean is still highly popular, but variation Senan, an Anglicized spelling of diminutive Seanan, is also stylish in Ireland. While Sean is the Irish form of John, Seanan and Senan may be thought of either as Sean diminutives or relatives of the Latin word "senator".

Hank is a midcentury guy nickname (which actually dates back to the seventeenth century) of the Al/Hal/Dick school, which has been on recess from the playground for decades. Now it's just beginning to be given on its own again, appreciated for its earthy, sportsguy cool. Hanks Aaron and Greenberg (born Henry) and Hank Williams (born Hiram) Sr and Jr. are worthy namesakes.

A place name with a deep Southern accent, the once-obscure Savannah shot to fame, with others of its genre, on the heels of the best seller Midnight in the Garden of Good and Evil, which was set in the mossy Georgia city of Savannah. Originally a substitute for the overused Samantha, Savannah is now popular itself, long among the top girls' names starting with S.

Joy is from an older generation of word names, which also included Merry, Bliss, and Glory -- all of which exert a certain amount of personality pressure on a child. However, Joy, like Grace, Hope, and Rose, has crossed more into name-territory than other word choices, which lightens some of that pressure.

Jason, the Number 3 name for the entire decade of the 1970s -- thus the title of our original baby-naming book, Beyond Jennifer & Jason -- is more likely to be dad's name now than baby's, but it's still a widely used name.

The sweetest and most sensitive of the pet names for Elizabeth, now also one of the most dated.

The unisex Blake, which indeed has two conflicting meanings, has a briskly efficient image when used for a girl.
