An excerpt from a Social Security Agency press release about popular baby names of 2007:
For reasons likely to puzzle baby name experts around the world, American parents have become infatuated by names, particularly for their sons, that rhyme with the word "maiden." These names for boys include: Jayden (No. 18); Aiden (No. 27); Aidan (No. 54); Jaden (No. 76); Caden (No. 92); Kaden (No. 98); Ayden (No.102); Braden (No.156); Cayden (No.175); Jaiden (No.191); Kaiden (No. 220); Aden (No. 264); Caiden (No. 286); Braeden (No. 325); Braydon (No. 361); Jaydon (No. 415); Jadon (No. 423); Braiden (No. 529); Zayden (No. 588); Jaeden (No. 593); Aydan (No. 598); Bradyn (No. 629); Kadin (No. 657); Jadyn (No. 696); Kaeden (No. 701); Jaydin (No. 757); Braedon (No. 805); Aidyn (No. 818); Haiden (No. 820); Jaidyn (No. 841); Kadyn (No. 878); Jaydan (No. 887); Raiden (No. 931); and Adin (No. 983). This startling trend was present, but less pronounced, with girls names: Jayden (No. 172); Jadyn (No. 319); Jaden (No. 335); Jaiden (No. 429); Kayden (No. 507); and Jaidyn (No. 561). Social Security spokesman Mark Lassiter indicated that the agency would resist any legislative efforts to standardize the spelling of these names.
I remember when we were taking Sophie home from the hospital in 2000, that a duo of new mothers were discussing their babies' names. One was "Jayden," the other "Craydon." Why Craydon? Because "Kayden" was already taken by a cousin!
