And "Tiffany" may sound like a very 20th-century American name, but it actually dates back to the early 13th century and is based on a Greek word that's even older. The "Tiffany Problem" is a really interesting phenomenon in the anthropological/perceptual space based on that.

Tiffany ← Tifinie ← Θεοφάνεια = "God's arrival/appearance"

It's also more closely related to the name "Natalie" than you might think, at least etymologically.

Natalie ←Natalia ←natale domini = "birth of the Lord" (Latin)
