According to the entry on Archduke Robert (father of Prince Lorenz of Belgium), his third child, Archduke Gerhard (1957) has married Archduchess Natalie Karoline of Austria, only daughter archduke Ladislaus of Austria (who is said to be the son of Joseph Augustus of Austria. )
- Archduke Anton Karl Ludwig Georg Felix Marcus d'Aviano of Austria ( 29 August 1976-)
Gerhard does not have a son. There is no archduke Ladislas.
Here is a link to a photograph of the alleged Archduke Anton. http://commons.wikimedia.org/wiki/File:S.K_u_S.K.h_Anton_-_Karl_von_Habsburg_-_Lothringen.jpeg
Fake, fake, fake. I repeat: Archduke Gerhard has not married. He does not have a son. No Archduchess Natalie.
