Gough has gone further than Fuller with regard to the interpretation of events in the north, believing that there is no evidence of polyandry in that area at all. She argues that all European travelogues describing polyandry came from the region of Central Kerala. Gough notes the differing personal experiences of earlier Nair commentators and that this could go some way to explaining the varied pronouncement: Panikkar, who queries the existence of polyandry, comes from the northern Travancore region; that A. Aiyappan, who acknowledges its existence, comes from Central Kerala; and that both have based their writings on customs they grew up with in their very different environs.
