Blaik is of Scottish origin, meaning 'clear' or 'fair'. It's an ancient name, derived from Old Norse elements blaekr and kiljar, signifying 'dark' and 'river', respectively. While it was historically used as a surname, Blaik has started to appear more frequently as a given name in recent times.
"Blaik was quite popular among parents in the late '90s and early '00s, peaking with ten babies born in 2008."
