Around 7 years ago, I was visiting Chicago's Navy Pier and found a coat of arms place. They guy did a quick search in his database and found our name in it. We printed out the coat of arms. In all seriousness, I really hope its correct because I have not been able to find it anywhere else.
Here's a quick description.
-its a simple yellow "heater" style medieval shield
-a large red chevron pointing up in the middle of the shield
-a small black wolf in the upper portion of the shield above the chevron
-three blue circles in a triangle formation in the lower portion of the shield below the chevron
-the picture also has some fancy looking red and yellow flare with a medieval knight profile above the shield (honestly, I think that could just be added on, but I don't know)
It also came with a brief history of the origins of the family name in Spanish with a brief description of the symbols on the shield. The information is not to substantial, but it's something.
I hope this helps.
