"Blend of Jay and Sean"
The name Jaysean is commonly a male name.
Jaysean is a modern American formation that reads as a combination of Jay and Sean, the Irish form of John. The Sean ending is what separates the spelling from the more common Jayson and Jason. It entered US birth records in 1989, which fits a late twentieth century coinage rather than an older established name.
The pronunciation of Jaysean is JAY-shawn.
