) is quite a rare principally masculine, but very infrequently female forename. The first name Jillu is habitual in Western Asia, particularly Oman, where it is a rare masculine name, Saudi Arabia, and Kuwait. In absolute terms, it is commonest in India, Bangladesh, and Saudi Arabia. Very seldom, Jillu is the last name as well as the forename.
