Throughout the world, Duval (Duval , دوفال , Дувал , along with others...) is a common principally masculine, but scarcely girly given name. The forename Duval is characteristic of Sub-Saharan Africa, particularly Reunion, where it is quite a common feminine name, the Democratic Republic of the Congo, where it is quite a common masculine name, and Cameroon, where it is quite a rare principally male, but scarcely feminine name.
