All around the world, Dalcy (Dalcy 
) is quite a rare dominantly female, but seldom boy's forename. The first name Dalcy is habitual in Bolivia, where it is quite a common principally female, but very infrequently boy's name, the Democratic Republic of the Congo, where it is a rare girly name, and Brazil, where it is a rare epicene name. Very seldom, Dalcy is the last name as well as the forename.
