Some Chembadis regard Gurappa Gurunathadu as their caste deity, and connect him, for some unknown reason, with the jammi tree (Prosopis spicigera). Jammi occurs as the name of a gotra, and some children are named Gurappa or Gurunathadu. When such children are five, seven, or nine years old, they are taken on an auspicious day to a jammi tree and shaved, after the tree has been worshipped with offerings of cooked food, etc. At the betrothal ceremony in this caste, immediately after the girl has taken up areca nuts, placed them in her lap, and folded them in her cloth, the headman takes up the betel leaves and areca nuts (thambulam) before him with crossed hands. This ceremony corresponds to the thonuku thambulam of the lower classes, e.g., Malas and Mangalas. Among the Mangalas and Tsakalas, the thambulam is said to be taken up by a Balija Setti. For the funeral ceremonies, the Chembadis engage a Dasari of their own caste. During their performances, flesh and toddy may not be offered to the deceased person. Chembian.--A name assumed by some Pallis or Vanniyans, who claim that they belong to the Chola race, on the supposition that Chembinadu is a synonym for Chola. Chembillam (chembu, copper).--An exogamous section of Mukkuvan. Chembotti.--In the Madras Census Report, 1901, it is stated that the name Chembotti is derived from "chembu, copper, and kotti, he who beats." They are coppersmiths in Malabar, who are distinct from the Malabar Kammalans. They are supposed to be descendants of men who made copper idols for temples, and so rank above the Kammalans in social position, and about equally with the lower sections of the Nayars. The name is also used as an occupational term by the Konkan Native Christian coppersmiths. In the Cochin and Travancore Census Reports, Chembukotti is recorded as an occupational title or sub-caste of Nayars who work in copper, chiefly in temples and Brahman houses. In the Gazetteer of the Malabar district, the Chembottis are described as copper-workers, whose traditional business is the roofing of the Sri-kovil, or inner shrine of the temple with that metal. They are said to have originally formed part of the Kammalan community. "When the great temple at Taliparamba was completed, it was purified on a scale of unprecedented grandeur, no less than a thousand Brahmans being employed. What was their dismay when the ceremony was well forward, to see a Chembotti coming from the Sri-kovil, where he had been putting finishing touches to the roof. This appeared to involve a recommencement of the whole tedious and costly ritual, and the Brahmans gave vent to their feelings of despair, when a vision from heaven reassured them, and thereafter the Chembottis have been raised in the social scale, and are not regarded as a polluting caste." Chembetti, or Chemmatti, meaning hammer, occurs as an exogamous sept of the Telugu Yanadis.
