Adelyn
Meaning
modern elaboration of Adeline, "noble"
The story
Adelyn belongs to the Ada dynasty: Ada the root, Adalynn, Adalyn, Adaline and Adelaide the queen stand beside this spelling, each charting separately, the shared sound one of the era's largest. Like Adaline, Adelyn keeps a secret flicker in the old ledger, about 140 a decade in the 1910s and 1920s, before vanishing at midcentury. The rebirth: about 2,500 in the 2000s, 14,000 in the 2010s, and 6,400 so far this decade. In our records it goes to girls about 23,600 to six, all girls this decade. The noble root is the same as all its sisters'; the -lyn finish is the trusted one; the only question left for a family is typography, and the record shows thousands answering it this way every year. One dynasty, many hands writing the same sound.
