After ten years of investigation I have identified 41 continuous generations from 650 A.C. My family comes directly from the main branch in Portugal. In the XIII century the cief of family and their brothers went to Castilla to be finally established in Baeza (Jaen Spain)in the XV century. I have not notice about Acunas emigrated to Americas. A remark for all the Acunas: the correct surname is "DE ACUNA", not only "ACUNA". A very best regard for all. Jose Maria de Acuna Torres.
