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.

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.

Derek started out as a sophisticated Brit, but the name became so common over the last decades of the twentieth century that it lost much of its English accent, along with its stylish edge. Derek was a Top 100 name in the U.S. for 25 years, from 1970 to 1995, after which it began to decline.

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.

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".

Linda will live forever in baby name history for toppling Mary from its four hundred year reign as Number 1. Queen of Names in 1947, Linda has fallen even further in favor than Mary today.

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys.
