Princess Marie Louise of Bulgaria

She married Prince Karl of Leiningen (2 January 1928– 28 September 1990) in a civil ceremony on 14 February 1957 in Amorbach and in a religious ceremony on 20 February 1957 in Cannes.

The couple had two sons:

Princess Marie Louise of Bulgaria (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.

After the change in house laws into absolute primogeniture by her brother King Simeon II, Princess Marie Louise became the head of the house of House of Saxe-Coburg and Gotha-Koháry.

Her godfather was Aleksandar Malinov.

She was enrolled at the Medical Nurse College of the Spanish Red Cross Society, which she graduated with honours.

After the abolition of the monarchy in 1946, Princess Maria Louise left the country with her mother and brother.

They first lived in Egypt and then moved to Spain.

Karl and Marie Louise divorced on 4 December 1968.

On 16 November 1969, she married Bronisław Tomasz Andrzej Chrobok (born 27 August 1934 in Katowice, Poland), in Toronto, Canada.

Subsequently they lived in New Jersey, United States and have a daughter and a son:

In 2001, she visited and toured the church of St John of Rila the Wonderworker in Chicago's Portage Park community area.

On 13 May 2012, at the 18th commencement ceremony, Princess Maria-Louise received an honorary doctoral degree in Humane Letters from the American University in Bulgaria.

The title "Princess of Koháry" was nominally ceded to Princess Maria-Louise and the descendants of her second marriage, by her brother King Simeon II, in September 2015.

Princess Maria-Louise is a member of the Board of Trustees of the American University in Bulgaria.
