villavar theory i strongly suspect the reliability of the citation provided it is a book titled history of kerala written by r leela devi and published by vidyarthi publications vidyarthi publications is primarily a publishing house of school guides so i think it does not fit for wikipedia reliable sources even if we take the book into account it says only this no reference given to the above statement in the book nor it says who are these some hence we are forced to consider it as either original research or weasel words i will be tempted to delete the above sentence along with all other mentions of villavar from the article if someone could not come up with a reliable reference to support the connection between ezhavas and villavar or at least claims of it
