Sydney

The name derives from an Old English placename compounded from sīd, meaning wide, and ēeg, meaning island or meadow. It spent centuries as an English surname and masculine given name before entering American birth records in 1880. By the 1990s, the spelling with two ys turned decisively feminine, shifting almost entirely into the girls' ledger.

A Sydney is pictured holding an iced drink, wearing athletic fleece, and keeping track of everyone's departure times. The name reads as turn-of-the-millennium momentum, carrying the energy of travel soccer tournaments and digital point-and-shoot cameras. With an estimated average age of twenty-four, the typical bearer sits squarely in Generation Z. She has spent most of her life watching people hesitate over which vowel to make a y.
