Ferdinand is a traditional name among Spanish royal families and also appears in Shakespeare's The Tempest, borne by the handsome young prince shipwrecked on Prospero's island. Bold, daring, and poetic, it was a popular choice in the US in the 19th and early 20th century, but the 1938 movie Ferdinand the Bull has left it with a lingering clunkiness and it has been out of style since the 80s.

If you discount the connection to the controversial Whittaker Chambers in the days of the Red Scare, Whittaker is a pleasant enough British surname with the preppyish nickname Whit.

Leandro is a variation of the Ancient Greek name Leander, created by combining the Latin words leo and Andro together, to get a meaning that suggests strength, power, and bravery.

The name St. John is much more usable in its phonetic spelling — similar to the way St. Clair evolved into Sinclair. St. John has some literary cred — St. John Rivers is a cool character in Jane Eyre.

The epithet of the legendary king's father Uther in Arthurian legend, later also applied to King Arthur himself.
