Well, I could write something, it doesn't mean that it is true. If you dont have historycal documents to confirm your words, it isn't historycaly acurate. There is a lot so called "orders" formed just to collect some money for "charity", donations, or simmilar. Where is document of founding that order?
There is a hundreds-thousends web sites about some knight orders, but that doesn't mean they are historycal orders.
Again, if you dont have relevant document to confirm your words, not some "copy" from 400-500yrs later, it cant be historycal.
Even if you Google a little, you can't find any relevant info about that order.
P.S. Where is that city Viso(e)grad in Hungary, where this order is founded? Was it some important city for HU at that time?
