History & Origin

Brynlyn is a modern coinage built from two real Welsh words. Bryn means 'hill' and is used as a given name in Wales; llyn means 'lake' and lies behind the enormously productive -lyn/-lynn ending in U.S. naming. Joined together they make a fresh compound rather than an inherited Welsh name, which we note honestly (said 'BRIN-lin').

It appears only in very small numbers in the U.S. Rare, crisp, and newly emerging.

Did you know? Both halves of Brynlyn are genuinely Welsh words - bryn is a hill and llyn is a lake - though the name itself is a modern American invention.
