"Blend of Jae and Lynne"
The name Jaelynne is commonly a female name from the "English" origin.
Jaelynne is a modern American formation built from two name elements: Jae, a spelling of Jay that also stands alone as a given name, and Lynne, a variant spelling of Lynn. Attaching Lynn or Lynne to a short first element is a familiar pattern in girls' names created in the United States in the late twentieth century, and Jaelynne fits that pattern rather than deriving from an older established name. It first appears in US birth records in 1996.
The pronunciation of Jaelynne is JAY-lin.
