Possible son for Diego Delgadillo & Petrona Ysla

I would like to know what all of you think. I found a possible son for Diego and Petrona. I have: George Delgadillo,
George Delgadillo & Clara Alvares
Married 1 June 1698 in Nochistlan Image #90.
Does not state Parents, but it has Padrinos as Andres Marin de Penalosa and Ma. de la Concepcion Delgadillo. And they married 28 July 1692 in Nochistlan Image #26. It states she is Diego's daughter.
I found a Dispensa for Jose Maria Ximenes and Bacilia Sandoval, 1798 posted Feb 7 film #168101 Image #208 that states George Delgadillo and Christoval Delgadillo are brothers, Christoval is the son Ygnacio Delgadillo and Josefa Manuela Ballin. I do not have definate prof, but what do you think? I hope I have not confused any of you.

Many Thanks
Lisa
