Born in
Paris on 11 March 1963, Sylvia Valentin was barely two months old when her parents were transferred to
Douala for work. She is the daughter of Édouard Valentin (died on 28 January 2019), a French businessman who headed the group called ''Omnium Gabonais d'Assurances et de Réassurances'' (OGAR, Gabonese Insurance and
Reinsurance). Her mother, Évelyne Valentin, then became President Bongo Ondimba's secretary. Sylvia spent most of her childhood in
Cameroon along with her siblings, before the family took up residence in
Tunisia. In 1974, after a long stay by the Valentin family in Tunisia, Sylvia and her parents decided to move to
Gabon, where she received an academic and
Christian education at the Libreville Immaculate Conception Institution. In 1988, Sylvia met Ali Bongo Ondimba. They married in 1989. They have three children:
Noureddin Edouard, Jalil, and Bilal, adopted by the couple in 2002. Malika is the president's first daughter from a previous relationship. On 16 October 2009, as Ali Bongo Ondimba was elected president, Sylvia Bongo Ondimba became Gabon's First Lady. Her grand-children are Elizabeth, Deborah and Dyah Bongo. ==Education==
