Looking for Anastacio Delgado Family

This is my greatgrandfather and I really don't know where he came from, but I remmber him as a child. He was light complextion, blue eyes, appeared to me to look Spainard or Mix Spainard/German or some type of european ethic. He became blind in his old age and my grandmother never told her mothers name. My grandmother had one sister and one brother. I do know that he remarried, but not sure. My grandmother told me that her mother die or left them and my greatgrand father had another wife. His name was Anastacio Delgado, he die in Phoenix Arizona.
