Antonio,

I'm afraid my uncle's mother's name was Juana "Maria" Ruelas Fierro. She passed away this past January. Her funeral was the first time I met my tio. I am not sure when he was born, but it definately was not 1958 because that was when my father was born and my tio is atleast ten years older than him.

I am very sorry I could not be of more help.
