In the world, Gisca (Gisca 
, Гисца 
) is quite a common predominantly girly, but very infrequently boy's first name. The first name Gisca is habitual in the Democratic Republic of the Congo, where it is quite a rare predominantly girly, but scarcely boy's name, Romania, where it is a rare epicene name, and Indonesia, where it is a rare dominantly feminine, but infrequently male name. Much less frequently, Gisca is the last name as well as the forename.
