Boys

Leander was once an almost unknown name, however, with the popularity of Leo and the rise of Leandro, it now feels like a perfectly accessible alternative to Leon or Alexander. In Greek legend, Leander was the powerful figure who swam across the Hellespont every night to visit his beloved Hero, a priestess of Venus.
 Combining the Latin words Leo and Andros, this name has a cool, animal-related meaning, that lends it strength and bravery. A once familiar name in the US, it fell out of favor back in the 40s, though in the last decade, it has nearly doubled in use with almost 120 babies receiving the name in 2023.
 
While Leander is in the Norwegian Top 100 and the Nameberry Top 200, elsewhere, the Spanish variant Leandro or the French Leandre tend to be favored.

Lysander is a distinctive Greek name that could be thought of as a more creative cousin of Alexander. In ancient history, Lysander was the name of an esteemed Spartan naval commander and his literary cred comes from one of the two star-struck young men in Shakespeare's A Midsummer Night's Dream, as well as one of the twin sons (the other being Lorcan) of Luna Lovegood, whom we learn about in the Harry Potter epilogue.
 Previously confined to the nurseries of Mayfair and Belgravia, we think Lysander could easily emigrate to the playgrounds of Park Slope.

Also spelled Macsen, this ancient name manages to sound modern and cool.  An heroic namesake was Maxen Wledig, a fourth century Spanish-born general who led the Roman army out of Britain, and as Emperor was the most powerful occupant of the throne of the Caesars who had ever ruled Europe from the City of the Seven Hills.
