Girl name list

A laid-back cowboy name which feels both cool and gentle, Dallas has ranked in the US Top 500 since records began in 1880. Never super popular but surprisingly never out of style, Dallas is given to nearly 1400 boys in the US every year.

Dylan still feels poetic and romantic after years of popularity. It still ranks highly on the charts, among the top boy names starting with D, so if you choose it, be aware that yours may not be the only Dylan in his class.

Fallon was one of the first of the unisex surname names, but thanks to "Dynasty" in the 1980s it now has a feminine image. For a boy, try Phelan instead.

Riley -- one of the most popular unisex names -- is trendier now for girls though for boys it's a classic, ALWAYS ranking in the US Top 1000.
