Was Cezhiyan Cendana a Pandyan king?

There is no way for me to find out if Cezhiyan Cendan was a Pandyan king or not. The only source I can find is a blog saying so. The problem is that texts in Wikipedia make me doubt. The text in the article for Maravarman Avani Culamani states that he is succeeded by his son Jayantavarman.

One fun fact is that templates do not have sources. It is however what I base information on when I add information to Wikidata. The other interesting point is that dates given are overlapping to the extent that they are not reliable.

So this is where we get into a problem. When information is good enough for a Wikipedia, is it good enough for Wikidata. More importantly is the question how do we curate information like this in a way that helps us all?
