Where it comes from
From dylan to Dylann
The story of Dylann
The Mabinogi gives Dylan four sentences: he is born to Arianrhod, is baptized, immediately makes for the sea, and swims as well as any fish in it, and the sea does not break beneath him. He is later killed by Gofannon in a blow whose story the text does not give. The name was revived in the twentieth century, carried by Dylan Thomas, born 1914, and then by Bob Dylan, who took it in the 1960s; American use follows both. The move to girls is recent, and the doubled n is the marker; Dylann's best year on the female side is 2016.
Meaning
sea, great flow
Welsh dylan, generally read as sea or as a great tide or flow. In the fourth branch of the Mabinogi, Dylan ail Don, Dylan the second wave, takes to the water at birth and is later killed by his uncle. The doubled n of this spelling is a modern American addition marking the name as a girl's, and it carries no meaning.

- counting every spelling
The SSA counts spellings, not names. Dylann went to 16 girls in 2025, but Dylan, Dillan and Dyllan are the same name said out loud. Together the 4 spellings went to 370, which makes it the 614th most-given girls’ name of the year — 6,224 places above the chart.
About 1 girl in 4,344 born in 2025 was given one of these spellings — against 1 in 100,454 for Dylann itself.
Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method
