All over the world, Силла (Sylla 
, Silla , Cilla 
) is a common epicene forename. The forename Силла is habitual in Sub-Saharan Africa, particularly Gabon, where it is quite a common masculine name, the Republic of the Congo, and Senegal, where it is quite a common primarily male, but very seldom female name. Not in comparison with a country's population, it is commonest in the Democratic Republic of the Congo, India, and Senegal. More frequently, Силла is the last name as well as the forename.
