In all the world, Oll (Olt 
, Oll 
, Олль 
) is a rare largely masculine, but uncommonly girly forename. The first name Oll is habitual in Albania, where it is quite a rare masculine name, Romania, where it is a rare male name, and Morocco, where it is a very rare female name. Not in comparison with a country's population, this name is the most popular in China, Albania, and Indonesia. More prevalently, Oll is the last name as well as the forename.
