The Habsburg Family jaw -an incest muddle

The Habsburg Jaw was a very distinctive deformity which was associated with one of Europe’s more powerful dynasty ”the Habsburg”.

Apart from the Habsburg Jaw, many other deformities such as the Habsburg lip – a protruding outward facing lower lip, as well as the Habsburg nose – a huge downward turning nose were also well known. All the names are derived from the famous Habsburg Dynasty.
