"Blend of Jo and Vaughn"
The name Jovaughn is commonly a male name from the "American" origin.
Jovaughn is a modern American formation rather than an inherited name. It joins the Jo- element found in names such as Joseph and Joel to Vaughn, an English surname-derived given name, and the -vaughn spelling matches that second element. The name first appears in United States birth records in 1977.
The pronunciation of Jovaughn is joh-VAWN.
