Deciphering another marriage certificate

On the marriage certificate for Nicolas de Robclaba y Juana Ruis de Luna, I can read all the information except the name of Juana's mother. It looks like Ma - but then I can't make out the next word. Any ideas are appreciated. It's the certificate in the upper left.

And is anyone familiar with either of these families? I can't find an earlier certificate for Nicolas and Maria Dias, so I don't know who his parents are.

Thank you.
