As far as I understand it, this is Hebrew Numerology, right? It must figure into occult practices a lot and at the least, probably George, Maria and Kinzo know of this stuff.

If I remember correctly, people liked to use this method on their names as they thought there was some kind of significance to it. For example in Revelations the idea was that you were supposed to calculate the number of <something or someone> to arrive at 666.
