Hi, my name is Tom S. Aguinaga. I'm one of the California Aguinaga's. I have been doing some family research and I'm willing to share some findings. "Aguinaga" Spanish form of Basque aginaga: topographic name for someone who lived near a group fo yew trees, from Basque (h) again yew + the collective suffix-aga."
My ancestors came from Matanzas, Jalisco or otherwised called Ojuelos de Jalisco located between San Luis Postosi and Aguascalientes. It appears to be a hub of Aguinagas there. My great-great grandfather was Juan Guerra Aguinaga. He's brothers, that we are aware of were, Hilario, Eusbio, Julio, Victoriano. He had five other brothers that we have not identified.
The earilest possible Aguinaga could be Juan de Aguinaga. He and Maria De Palacio had Jose Aguinaga in "July of 1639! My family imigrated through El Paso in May of 1918. My grandfather worked in the Railroads through the south west, until settling in Calexico, California. There may be other Aguinaga's in Calexico now but my family has settled throughout California now.
For Melissa in Milwakee. I know how you feel. If anyone has information pertaining to the Aguinaga surname or any family links. Please let me know. Thanks Tom.
