I'm late for this discussion (which is literally because I forgot to comment here), but this is the origin of the name "Grigori". "Shemihaza" is an incorrect romanization of シェムハザ (Shemhaza), an alternative (and the Japanese) name of the angel Samyaza (Shemihaza/Shemihazah is an alternative name too), which is the name the wiki decided to use. With that said, I assume the other Grigori are also named after the biblical watchers (though there is no way to guess who is who, so we shouldn't speculate).

Also, aren't there more Grigori other than the main three?
