"Blend of Jayce and Lyn"
The name Jaycelyn is commonly a female name from the "American" origin.
Jaycelyn is a modern American formation built from the name Jayce, itself a respelling of Jace, plus the suffix -lyn that appears in many twentieth-century American girls' names. The name is transparent in form rather than inherited from an older language, and it carries no meaning beyond those parts. It is not an established name in any documented naming tradition.
The pronunciation of Jaycelyn is JAY-suh-lin.
