Saint Dominic was born in Caleruega, Spain in 1170. His parents were members of the Spanish nobility and related to the ruling family. His father was Felix Guzman, and was the royal warden of the village. His mother, Bl. Joan of Aza, was a holy woman in her own right.
The animal seemed to set the earth on fire. His parents named him Dominic a play on the words Domini canis, meaning the Lord's dog in Latin. An alternative, and possibly more likely story says he was named after St. Dominic de Silos, a Spanish monk who lived a century before.
