Miguel de Fuenterrabía was born some time between 1519 and 1524, making him somewhere between sixteen and twenty-one years old when he went on the Expedition. On the 1540 muster he was listed as a footman. After the Expedition he returned to Mexico City, Miguel again enlisted in the conquest of Nueva Segovia (Nicaragua). From the mid-1550s to the end of the 1570s he was a vecino in Mexico City. There are no other individuals with this name in the known documentary record.

Fuenterrabía is on a spit of land in the Atlantic just on the French border, Basque country. Could he be a son of Juanes de Fuenterrabía who was from Fuenterrabía and who was in Cuba in 1518?
