"Blend of Roz and Lynn"
The name Rozlynn is commonly a female name from the "American" origin.
Rozlynn is a modern American formation rather than a name inherited from an older naming tradition; it first appears in United States birth records in 1971. Its two parts are Roz, a short form of names such as Rosalind and Rosemary, and Lynn, an established given name. The z spelling points to the Roz element rather than to a Ros- spelling.
The pronunciation of Rozlynn is ROZ-lin.
