Seren is a top girls' name in Wales – and a lovely choice almost unknown elsewhere. Seren, in the Sirona form, was an ancient goddess of the hot springs.

Lula has a firecracker personality, a singing and dancing extrovert. Interesting that Lulu was a Top 100 name when the Social Security list was born in 1880, but it's been sliding ever since and has not been in the Top 1000 for decades. Modern parents in love with Lulu might well reverse that trend.

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names. Grey/Gray is one exception, which could make for a soft and evocative—if slightly somber—choice, especially in the middle. Kaitlin Olson and Rob McElhenney named their son Leo Grey.

Marlo first came to prominence as a perky, pretty nickname name that seemed to have been invented by or for Marlo Thomas, who was born Margaret. But Marlow and Marlowe are English surnames meaning driftwood, are more popular forms of the name, giving it historical depth and a nature meaning. And Marlo is the most truly gender-neutral, given to about 100 babies of each sex last year.

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

Kaitlin Olson and Rob McElhenney recently named their son Leo Grey.

A few decades back, this name -- which hardly shows its Irish roots -- evoked a man in a gray flannel suit; now, though still upscale, it's more likely to be attached to a female.

Nicola, an elegant Latinate feminization of Nicholas, has long been standard issue for English girls but for some reason has never voyaged across the Atlantic, which we consider a pity, especially as Nicole's standing has waned.

Dash is a nickname that can stand on its own and sounds, well, dashing. Connected these days with Kardashian enterprises.

Though Tristan was the male figure in the romantic legend and his name has become trendy for boys, it's used now for girls, too: About 15 percent of the baby Tristans are female. And about three times as many girls are named Tristan as are named Isolde, Tristan's mythical female counterpart. There are also feminizations of Tristan, such as Tristana and Tristine, but these are much more rare than the original.

One of the most attractive and unusual spins on the "Fran" franchise.
