"Blend of Ren and Leigh"
The name Renleigh is commonly a female name from the "American" origin.
Renleigh is a recent American formation that first appears in United States birth records in 2014. It joins Ren, a short form or name-part also found in Renee and Renata, with the ending -leigh, which derives from the Old English element leah, recorded in English place names and surnames with the sense of wood or clearing. The -leigh spelling belongs to twenty-first-century US coinages rather than to an older established name.
The pronunciation of Renleigh is REN-lee.
