"Blend of Jace and Lynn"
The name Jacelynn is commonly a female name from the "American" origin.
Jacelynn is a modern American formation that joins Jace with the element Lynn, the same -lynn ending found in other late twentieth century coinages such as Kaylynn and Braelynn. Jace itself is a twentieth century English given name, and Lynn is a common second element in American girls' names. The name first appears in United States birth records in 1995, which fits a recent combination rather than an inherited name from an older naming tradition.
The pronunciation of Jacelynn is JAYS-lin.
