One of those simple, straightforward English surnames -- and with a presidential pedigree -- that's easy to translate into a first. Chosen by both Kevin Costner and Jessica Alba for their sons, it has been climbing the US charts since 2009.

Hayes is a stylish surname name, reminiscent of vintage Hazel, contemporary Collins, nature-inspired Forest and Rivers, and older unisex favorites like Hayden, Reese, and Casey. While it has seen increased use for girls in recent years, it is predominantly used for boys.

Possible Hayden alternative.

Could be difficult to grasp: Hoss. The "Bonanza" cowboy.

An appealing alternative to Hayden and Hayes, perhaps in homage to Old Hollywood actress Rita Hayward.
