in my reseach, the last name comes from asturias spain, in the northern region. there is even a "town" (4 house really) with the name. i have a foto if you wish i can send. there are 4 tamargo families in Tampa, where i live and a couple in Miami. our family came from cuba so i am having problems linking them back to spain, but i am certain that they are from there. please keep me posted on the information you gather, i would love to share what i have and perhaps make a link with yours! cynthia garcia tamargo, tampa, florida USA
