Princess Mafalda was born in London, England, in 1994. Her parents are Prince Kyril of Preslav and Princess Rosario Nadal, and she is the eldest of their three children. She has a sister, Olimpia, and a brother, Tassilo. Her father, Kyril, was born in Madrid, Spain, but also spent a lot of time in the U.S. after attending Princeton University. According to his official royal biography, Kyril has a physics degree and went on to work in corporate finance and banking for the Lehman Brothers in both London and New York between 1991 and 2001. This also explains why, despite her Bulgarian family ties, Mafalda was raised in England.
Prince Kyril married Mafalda’s mother, former fashion model Rosario Nadal, in 1989. However, after nearly 20 years of marriage, Kyril and Rosario separated in 2009, though they never officially divorced, according to Vanity Fair. Interestingly, the Bulgarian royals also have ties to the British royal family, as Kyril was reportedly close friends with the late Princess Diana.
