"Blend of Jay and Shaun"
The name Jayshaun is commonly a male name from the "English" origin.
Jayshaun reads as a combination of Jay, an English name, and Shaun, the Irish form of John. The spelling points to a modern American formation built from those two elements rather than to an older single-source name with its own recorded history.
The pronunciation of Jayshaun is JAY-shawn.
