Hi Robin, I have not authenticated the Aguayo crest, I wouldn't even know how to begin to do this. I do know that there were Aguayos among the conquistadores of the New World, so they were bound to have had family crests.
My grandfather, Luis Angel Aguayo Burboa, had blond hair and blue eyes. He was so fair skinned that he died of skin cancer. He had very red skin from sun exposure. He was from the state of Chihuahua, Mexico.
