From the experts:
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.
