Catalina de Osorio Mendoza - Any documentation on her?

I can only find that she was married to Francisco de Solís Osorio/ or Francisco de Sales Osorio who was Governor of Yucatan during the 1580s
They had four children: Pedro, Diego, María & Juana.

I can't find any info on her family outside of Geni & I suspect she was a bastard daughter of someone or she was added to the family. tree artificially.
