Our story of Marily
Before computerised registration a name was written by hand, often by a clerk hearing it aloud, sometimes twice in two different offices. Letters went missing, doubled letters were singled, unstressed syllables were dropped, and once the certificate existed it was the name. That process is visible all over the older data as a thin layer of near-names sitting beside the common ones: Marily beside Marilyn, Dorthy beside Dorothy, Cathrine beside Catherine, Geraldene beside Geraldine. Some are deliberate and some are accidents, and the record cannot tell them apart, which is the point. A name is whatever was written down, and a fair number of Americans have spent their lives with a version of a name that nobody meant to invent.
Meaningnot established
Not established
Marily is most plausibly Marilyn with the final n lost, whether by a writing slip or deliberately. Marilyn is itself a twentieth-century blend of Mary with the -lyn suffix. No separate etymology attaches to this form; the peak is 1945.

Three syllables, stress on the first. Without the final n the ending rhymes with Emily rather than with Marilyn.

The Julio test
Every popular name lives one long story — a climb, a peak, a slow settling back. Marily's later chapters haven't been written yet, so we borrowed them: Julio climbed just as high around 1923, and its whole arc is on record. Line the two peaks up, and Julio's path sketches the road Marily is walking now.
