Across the world, Morno (Morne 
, Mornu 
, Morno

The first name Morno is characteristic of Namibia, where it is quite a rare male name, South Africa, and Australia, where it is a rare male name. In absolute terms, it is commonest in Sub-Saharan Africa, particularly South Africa, Namibia, and Nigeria. Much less frequently, Morno is the last name as well as the forename.
