About Princess Maria Luisa, 9th Princess of Koháry
Princess Marie Louise of Bulgaria (Bulgarian: Княгиня Мария Луиза Българска; born 13 January 1933) also known as Marie Louise Borisova Saxe-Coburg-Gotha, is the daughter of Tsar Boris III and Tsaritsa Ioanna and the older sister of Simeon II of Bulgaria. Her baptism in the Bulgarian Orthodox Church caused controversy at the time because her mother had promised to raise her children as Catholics.

With her brother, she took part in the ship tour organized by King Paul of Greece and Queen Frederica in 1954, which became known as the "Cruise of the Kings" and was attended by over 100 royals from all over Europe. === Marriage and issue === She married Prince Karl of Leiningen (2 January 1928, Coburg, Germany – 28 September 1990, Vered Hagalil, Israel) in a civil ceremony on 14 February 1957 in Amorbach and in a religious ceremony on 20 February 1957 in Cannes.
