Who Is Asritha verch Llandilo, Supposed Wife of Maredudd ab Owain?

Question

On WikiTree, Maredudd ab Owain is shown as being married to "Asritha verch Llandilo."  I can't find a source for the existence of this person, but I'm sure Maredudd was married to someone.

Is there a source for Asritha?  Who was the wife of Maredudd ab Owain?

Answer 1

According to Medieval Lands the name of Maredudd's wife is unknown and a couple of other sources don't mention his wife including the Dictionary of National Biography

and the Welsh Biography Online

A Google search for Asritha, only found unsourced online genealogies, and unless someone else can find a source, I think that somewhere along the line she has been 'invented' and Maredudd's wife should be Unknown.

Also Llandilo is a suburb in Sydney, New South Wales, Australia, and although it's named after a Welsh town, that town is actually named Llandeilo, which suggests Llandilo, Asritha's father may also be 'invented'
