The story of Aaron
The merger of the vowels in marry, merry and Mary is one of the defining features of most American English, and it is close to complete outside the northeast. Where it applies, Aaron and Erin are homophones. Erin rose sharply as an American girls' name through the 1970s, peaking in the early 1980s, and the female Aaron row rises and falls in the same years, with its best year in 1976. That is what a spelling error at scale looks like in a national dataset: a name that should not have a female side acquiring one exactly in step with a homophone that does.
Meaningnot established
Not established
Aaron itself has no accepted etymology and is probably Egyptian rather than Hebrew, like Moses and Phinehas. Erin, the name this row most likely represents, is from Eirinn, a case form of Eire, the Irish name for Ireland. The two names are unrelated in every respect except that most Americans pronounce them identically.

The Evon test
Every popular name lives one long story — a climb, a peak, a slow settling back. Aaron's later chapters haven't been written yet, so we borrowed them: Evon climbed just as high around 1954, and its whole arc is on record. Line the two peaks up, and Evon's path sketches the road Aaron is walking now.
