Brennan is a winning Irish surname name, more modern than Brian or Brendan, more unusual than Conor and Aidan. The only possible problem with Brennan: people might think you're saying Brendan.

Monroe is a presidential name which, thanks to the immortal beauty of Marilyn Monroe, is catching on fast for baby girls. Mariah Carey and Nick Cannon chose it for their twin daughter, honoring Marilyn Monroe. Their use of Monroe as a girls’ name did much to revive this Old Man name, a la Sydney, as a newly fashionable choice for girls.

In the past this was seen as a jokey Southern colonel name, but we have heard of some parents considering it as a path to the likeable Beau.

Fleur is a generic, delicate flower name that emigrated into the English-speaking world when John Galsworthy bestowed it on one of the Forsytes in his celebrated saga. More recently, there was Fleur Delacour, a French witch and the Beauxbatons champion for the Triwizard Tournament in Harry Potter.

Andre is one of the international forms of Andrew that has been familiar in the English-speaking world for decades without any need to be overly Anglicized - though round the world, it is more likely to be written as André.

A sassy, spunky, punchy kind of name, Dixie can also be considered a place name, one that has become problematic because of its association with the antebellum South. The Dixie Chicks recently dropped Dixie from their band name because of its association with slavery and white privilege.

Attractive entry into the tree name genre, joining Ash, Oak, and Juniper. Over 110 baby boys were named Cypress in the US last year, along with 70 baby girls.

Monroe is a presidential surname which feels fresher than Jackson, Lincoln and Taylor. Marilyn Monroe is a famous female namesake, but her smart Scottish surname feels equally usable for either sex. Plus, we think old man nickname Moe would sound both cool and adorable on a baby boy today!

Heron may feel like a very usable nature name -- the heron is a long-legged wading bird -- but it was also the name of a 1st century Greek inventor and of an Egyptian saint. Highly unusual yet easy to understand and meaningful on several levels, Heron is a fantastic choice.

Peaking in the 1950s, Yvonne has now dropped out of the Top 1000 in 2003 and doesn't look set to return soon, although its rare Y initial might endear it to some. Yvaine, from Neil Gaiman's Stardust, has more modern appeal.

St. Landry was a seventh century bishop of Paris, founder of the city's first hospital. The name is more familiar in recent years thanks to legendary Dallas Cowboys coach Tom Landry, an association that makes this a sports hero name, as well as a thoroughly masculine one. Landry is also in use for girls in the US. Landry is one of the oldest surnames in France, dating back to the medieval period, and is particularly popular among Cajun-Americans. It has been on the Social Security list since 2010.

Occupation names and spiritual names are in style, so it's hardly surprising that Bishop has been making appearances in the Top 1000. Popular back in the late 19th and early 20th century, it reappeared in the charts in 2015. Given to 170 boys in a recent year, it tends to drop in and out of the Top 1000.

Though it's used for boys, most non-French people would hear it as a girls’ name. Most would be surprised to learn that Rene has always charted in the US Top 1000 for boys.

Camellia is a rare flower name with distinct roots related to the Camille/Camila group and has varied associations to the moon, water, wealth, and perfection. It could be thought of as a floral replacement for Amelia.

These days, some may think of Hermes as an upscale brand name like Chanel and Porsche (spelled as Hermès), or a strange choice thanks to the parcel delivery company.
