I have traced the name from Spain to Mexico in the armies of Hernan Cortez. After Cortez conquered the Mayas and Toltec in Mexico, he split his military forces in two, keeping one half at the garrison in Tenochitlan (Mexico City), the other half he sent to South America to conquer the Inca. From there Ronquillo's were sent to the Phillipine Islands to establish trading concessions with the chinese and establish colonies.
