Having the same name does not mean, you can bear a coat of arms of that name. You have to be descendant of the original bearer. This site is pretending you can, just to make money. That's simply dishonest. Many coat of arms and informations are not correct, anyway - for example Lorberau is not the same as Lorber - these families have different coat of arms. So, don't trust that site.

I took the trouble of looking up the surnames mentioned in three of the references they cite. None of the surnames appear in any of the reference books I checked. Apparently, they cite the same bogus references everywhere to give an appearance of authority. Note that nowhere do they cite the exact page they got the information from.
