Shay is a genuine multi-origin name. Behind the Name lists it both as an anglicised Irish form of Séaghdha and as an alternate transcription of the Hebrew name Shai.
Because both routes are established, the safest published treatment is to present Shay as multi-origin rather than force one meaning. In Irish use it follows an older Gaelic name, while in Hebrew use it belongs to a separate established line.
