TRANSLATION:

The ancient site of this name was on the River Ebro near the town of Reinosa (Santander).  A descendant from this ancient site was a Don Rodrigo De Silos. He helped and fought in the struggles of the Seven Infants Of Lara* and died with them near Cordoba.

The Shield: A divided shield, the first vertical section has a silver tower built on similar silver rocks, and the second vertical section is gold with an ash tree and two hounds tied to its trunk.

My Notes:

I also heard that the name Silos existed in ancient Greece long before the name came up in Spain.  During a visit to Rhodos, Greece, I came across a Silos family who owned a grocery store.  I later met a lot of the clan!  They were  born and raised in Greece and so were their parents, grandparents and ancestors.  He said the Silos name was an ancient Greek name.  What a surprise!  He added "Silos" could have originated from the Greek words "Psilos" and "Ypsilos" and then later shortened by the Spanish and Portuguese descendants, who knows......
