Blair

Derived from the Scottish Gaelic blàr, signifying a plain, meadow, or battlefield. It functioned as a Scottish topographic surname for centuries before crossing the Atlantic as a masculine given name. American parents began reassigning it to girls in significant numbers during the late twentieth century.

The name lands like a boarding-school syllabus: single-syllable, dry, and entirely without decorative frills. It carries an air of East Coast autumns, tailored wool coats, and sharp rejoinders. While it spent decades as a quiet masculine standby, modern usage tilts noticeably toward girls born after the turn of the millennium. It reads as someone who keeps an immaculate desk and never loses an umbrella.
