Meaning:like a lion; loyal
Like many gender-neutral names, Dillon—which came about when the surname-as-first-name trend got under way in the latter 20th century—has since been claimed by one sex, and this time, it’s the boys who can declare victory. It’s pronounced the same way as the more popular Dylan, yet the two names aren’t related. Dillon is Irish and means “like a lion, loyal,” while Dylan is Welsh and means “son of the sea.” If you've got a boy, go with Dillon or Dylan; for a girl, Dylan.
