Finlay is a Scottish royal name: it belonged to Macbeth's father, Finlay MacRory--or Findlaech mac Ruaidri--that has a bit of a split personality.

It is also becoming more and more unisex in the States, with the Finley spelling now split between girls and boys, while Finlay was used last year for TEN TIMES as many boys as girls, about 50 to only five.

Madonna did much to polish up the image of this old-neighborhood Italian choice when she picked it for her son with British director Guy Ritchie, and several years later it was also used by Rose Byrne and Bobby Canavale for their son.

Fintan is an ancient Irish saints' name that in legend is also the name of the only person to survive The Flood. Popular in modern Ireland, Fintan is ripe for export to the US where it is rarely used but could make an excellent long form for the stylish Finn.

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names.
