Fair-haired meadow or dark lake clearing
A modern American invention, Blakelyn combines the surname-turned-first-name Blake with the popular suffix -lyn. It draws on the dual Old English roots of Blake, which can paradoxically mean both 'fair' and 'dark,' combined with the Welsh or English 'lyn' meaning lake or pool.
