Johanna von Klinkosch by Victor Angerer, ca. 1870s
Prince Aloys of Liechtenstein married in Vienna on 20 May 1890 Johanna Elisabeth Maria von Klinkosch (Vienna, 13 August 1849 – Baden bei Wien, 31 January 1925), daughter of the master silversmith Josef Carl Ritter von Klinkosch and his wife Elise Swoboda, without issue. She was then known as Johanna Prinzessin von und zu Lichtenstein.
She was the ex-wife of Albert Ottomar Haupt and the sister of Paula Szechenyi (see my other post here); Isidor Joseph Karl Klinkosch and Arthur Klinkosch.
