The genealogy, plus photographs and documents of ex-president Campo's family can be seen in the book "Salvadoran Roots" by Jaime Cader, published in 2011.

Photos included are those showing the military rank ("Teniente Coronel") and the Cantabria, Spain origin of the deceased father-in-law of Campo, Juan Antonio del Pomar.

Also included is information concerning the rank and name of the father of Campo's mother-in-law, "Teniente Coronel" Antonio Contreras.

He was in office during Central America's "National War" against William Walker and his filibusters, a very difficult time for that region.

The book "Apuntes Biogáficos del Honorable Ex-presidente de El Salvador -Don Rafael Campo" by Abraham Rivera (1985 edition) has a photograph of Campo with the caption saying that he is the enemy of foreign intervention in Central America.
