According to the Census Report, 1891, the main sub-divisions of the Kammas are Gampa, Illuvellani, Godajati, Kavali, Vaduga, Pedda, and Bangaru. It would seem that there are two main endogamous sections, Gampa (basket) Chatu, and Goda (wall) Chatu. Chatu is said to mean a screen or hiding place. Concerning the origin of these sections, the following story is told. Two sisters were bathing in a tank (pond), when a king happened to pass by. To hide themselves, one of the girls hid behind a basket, and the other behind a wall. The descendants of the two sisters became the Gampa and Goda Chatu Kammas, who may not intermarry by reason of their original close relationship. According to another legend, after a desperate battle, some members of the caste escaped by hiding behind baskets, others behind a wall. The terms Illuvellani and Pedda seem to be synonymous with Godachatu. The women of this section were gosha, and not allowed to appear in public, and even at the present day they do not go out and work freely in the fields. The name Illuvellani indicates those who do not go (vellani) out of the house (illu). The name Pedda (great) refers to the superiority of the section. Vaduga simply means Telugu, and is probably a name given by Tamilians to the Kammas who live amongst them. The name Bangaru is said to refer to the custom of the women of this sub-division wearing only gold nose ornaments (bangaramu). The Godajati sub-division is said to be most numerously represented in North Arcot and Chingleput, the Illuvellani in Kistna, Nellore and Anantapur. The Kavali sub-division is practically confined to the Godavari, and the Pedda to the Kistna district. The Vaduga Kammas are found chiefly in Coimbatore. In his note on the Kammas of the Godavari district, Mr. Hemingway writes that "in this district they are divided into Kavitis, Eredis, Gampas or Gudas, Uggams, and Rachas. These names are, according to local accounts, derived from curious household customs, generally from traditional methods of carrying water. Thus, the Kavitis will not ordinarily carry water except in pots on a kavidi, the Eredis except on a pack-bullock, the Uggams except in pots held in the hand, and not on the hip or head, the Rachas except in a pot carried by two persons. The Gampa women, when they first go to their husbands' houses, take the customary presents in a basket. It is said that these practices are generally observed at the present day."
