"Blend of Jay and Lynn"
The name Jaylenn is commonly a unisex name from the "English" origin.
Jaylenn is a modern American blend of Jay and the -lynn name ending, the same pattern seen in Kaylynn and Braelynn. The final double n is a respelling of the same combination that also appears as Jaylen and Jaylyn. It first appears in United States birth records in 2000, which fits a formation assembled from existing name parts rather than an inherited name.
The pronunciation of Jaylenn is JAY-len.
