The 1901 Madras Census noted three groups who called themselves Paravars. It speculated that their common root were the mostly Christian Tamil-speaking Paravars, The other groups were the Canarese-speaking Paravars, who were umbrella makers and devil-dancers and the Malayalam-speaking Paravars, who were lime burners, gymnasts, midwives and shell collectors. It has been further speculated that the splitting of the latter two groups from the first may have been as a consequence of a desire to move away from the ancient tribal area when faced with the arrival of Muslims.
