That is a very good post Silverdsd. Using numbers to find your name is certainly a way to get a magickal name. But there are other ways and it is best to spread out options to help those in need.
One way to get a magickal name is to go out into the world (mostly the woods) for about two weeks. Survive in there and learn what you can, speak to your spirit/guarden angel, and so much more. Of course this isn't used as much so it isn't number one choice.
Another way is having the parents pick the name for the child. They will look into different things about the birth and child and get a name for it. Of course after some time it gets kind of pointless to do this but is still an option for any wiccan/pagan/whatever parents.
The way I have done it, finding my name, is by looking at most of the names I can possible at the time and look at what it means. I picked out the one that means the most to me and my person.
There are more ways to find your name, like meditating or tarot cards. Just find the one you suit the most.
