Unique girl and boy names

Alba is quietly making a behind-the-scenes comeback, perhaps thanks to actress turned baby-product mogul Jessica Alba. Last on the Top 1000 a century ago, the name was given to nearly 200 baby girls in the US last year. Alba might be tomorrow's successor to Ava and Ella. In Spain, Alba ranks among the Top 20 girls' names. Alba is the name of a character in The Time Traveler's Wife.

Isla is a hit name throughout the English-speaking world but hasn't found the same popularity in other western countries, perhaps because its spelling and pronunciation don't make sense for those whose native language is not English. Think island without the final two letters.

Mila is a popular name that took a 125 year nap, ranking in the Top 1000 in 1881 and then not ranking again until 2006, after actress Mila Kunis appeared on That 70s Show.

Quinn is the Anglicized version of the Irish patronymic surname Ó Cuinn, meaning "descendent of Conn." Conn has two possible derivations—the Old Irish cond, meaning "intellect," or cenn, meaning "chief." One of the most notable Quinn clans was from County Tyrone in Northern Ireland.
