Illam. — Defined by Mr. Wigram *[1] as meaning the house of an ordinary Nambūdri Brāhman. It is recorded, in the Travancore Census Report, 1901, as a sub-division of Nāyar. The name Illam Vellāla has been assumed by some Panikkans in the Tamil country, whose exogamous septs are called Illam. In Travancore, Ilakkar or Illathu, meaning those attached to Brāhman houses, is said to be an occupational sub-division of Nāyars. Ilakkar further occurs as an exogamous sept of Mala Arayans, known as the Three Thousand.
