Ireland is full of beauty; from its picturesque scenery to its literature and music to its names harkening back to tradition, there is more than enough culture to cherish. If there’s some Irish blood flowing through baby’s veins, you’ll no doubt want a name to answer Ireland’s call! Caelyn is a girl's name meaning "little slender one," “slender and fair,” “pure," “clean,” or “clear.” It is a variant of three Irish names—Caolán, Caoileann, and Caitlín. Although it derives from popular spellings, the -lyn ending of Caelyn is a cute and modern twist.
