"Blend of Lynn and Leigh"
The name Lynnleigh is commonly a female name from the "English" origin.
Lynnleigh is a modern American formation that joins two established name elements, Lynn and Leigh. It first appears in United States birth records in 2008. The closing -leigh rather than -ley or -ly is a spelling choice characteristic of recent American coinages built from those elements.
The pronunciation of Lynnleigh is LIN-lee.
