Biography

Early life and education

Prince William was born in Belo Horizonte, Brazil, being the only son of Princess Nilza of Marienbourg to her husband Sebastião de Sousa. His mother is sister of the late Princess Maria III, which in turnes makes of William a first cousin of the late Princess Marilia IV and first cousin-once removed of Duke Arthur V.

Through is mother, William is a member of the Carvalho family, an ancient family of Portuguese origin that dates back to the 12th century. However, as Prince of Marienbourg, William was incorporated into the so-called House of Bruyn-Carvalho, a cadet branch of the House of Bruyn born through an agreement between his uncles Anthony and Edison Carvalho and his cousin Arthur van der Bruyn, by which Arthur, who is a Bruyn, became sovereign of Marienbourg and the Carvalho family, that of his mother, became his heirs.

Growing up in Belo Horizonte, William was very close to his cousin Marilia, which did not change throughout her life, even with the princess having moved from the Minas Gerais state in Brazil. Between 1973 and 1985 William attended Minas Gerais Baptist School, where his parents worked and lived as caretakers of the property. After graduating from high school, William took a series of courses in business, computers and human resources, and he didn't go to college, having specialized in these courses in order to get a secure job as quickly as possible.
