The story of Kelsey
Surname names crossing from boys to girls is one of the most regular patterns in modern American naming, and the crossings are usually fast. Kelsey entered the American boys' top thousand in the 1970s and reached its male peak in 1989; the girls' use began in 1976, overtook the boys' by 1980 and reached the top forty in 1992. Once a name tips it very rarely comes back — Ashley, Shannon, Whitney, Courtney and Lindsay all made the same journey and none returned. What the boys' record captures here is the last few years before the door closed.

Ceol's island
Old English eg means an island, or more often a piece of dry ground in marshland — the same element as in Ely, Bardsey and Chelsea. The first element is generally read as the personal name Ceol, from ceol, 'ship, keel'. So Kelsey is Ceol's island. There are Kelseys in Lincolnshire, and the surname derives from them. The first element is not fully secure but the island is.

The Butch test
Every popular name lives one long story — a climb, a peak, a slow settling back. Kelsey's later chapters haven't been written yet, so we borrowed them: Butch climbed just as high around 1952, and its whole arc is on record. Line the two peaks up, and Butch's path sketches the road Kelsey is walking now.
