Delaney
The story
Delaney is an Irish surname, O Dubhshlaine, whose meaning our records honestly mark uncertain, and its first-name life detonated in one decade: about 460 in the 1980s became 7,700 in the 1990s, seventeen times over, one of the sharpest single-decade turns in tonight's batches, with no single cause on record; the Irish-surname wave that carried Riley and Kennedy crested exactly then, and we decline to name one wave-maker. The crest came fast, about 17,300 in the 2000s, and the settling has been gentle: 13,000, then 7,500 so far this decade. In our records it goes to girls about 45,400 to 1,200. Laney does the everyday work. An uncertain meaning, a certain sound, and a reminder the record keeps offering: a surname's daughter can outnumber all its sons within a generation.
