Dalan is an intriguing and uncommon given name of unknown origin, though some suggest it may have Irish or Scottish roots. It's pronounced as /dɑːlən/ and consists of three syllables, making it a distinct and attention-grabbing choice for a personal moniker. Spelling variations include Dahlen and Dalen, but the most common form is Dalan. Although its popularity has not been widespread in English-speaking countries, it's not unheard of, appearing occasionally in birth records since the late 20th century.
"The name Dalan experienced a surge in popularity from the late 1980s to the mid-1990s, with peaks in 1988 (15 births) and 1993 (16 births). However, its usage has been relatively low since then, with fewer than 10 births per year from 1997 onwards. The most recent years have seen a slight increase, with 6 births each in 2022."
