Robert and Euphemia Gordon Carew were my great, great, great grandparents.

and I will share the information that I have with you directly.
PS: Highly unlikely that we are descended from David fitz Gerald (of Carew in South Wales), Bishop of St. Davids. More likely from his nephew, Raymond fitz William aka Raymond le Gros. But the truth is, we don't know anything for certain about our ancient Carew relations. We can with a high degree of certainty trace our Carews back to 17th century Ireland.
