Greetings everyone: I am looking for information about the mother of Mariana de Mendoza y Velasco. She was the wife of Capt. Francisco Tello de Lomas, whom she married on 19 March 1668 (no parents mentioned in the marriage record)

https://www.familysearch.org/ark:/61903/3:1:9392-D29Q-N2?i=10&cc=1874591

So far, her children’s records do not name grandparents. Her daughter (my 9th GGM) Gabriela Lorenza Tello de Lomas names her as Mendoza y Velasco in Gabriela’s marriage record (adding the “Velasco” part). Any help would be much appreciated. Thanks in advance.
