In this instance, however, he is in error. It has everything to do with
the author of "Don Quixote," for it is in fact these old walls that have
given to Spain the name she is proudest of to-day. Gonzalo, above
mentioned, it may be readily conceived, did not relish the appropriation
by his brother of a name to which he himself had an equal right, for
though nominally taken from the castle, it was in reality derived from
the ancient territorial possession of the family, and as a set-off, and
to distinguish himself (diferenciarse) from his brother, he took as a
surname the name of the castle on the bank of the Tagus, in the building
of which, according to a family tradition, his great-grandfather had a

Both brothers founded families. The Cervantes branch had more tenacity;
it sent offshoots in various directions, Andalusia, Estremadura, Galicia,
and Portugal, and produced a goodly line of men distinguished in the
service of Church and State. Gonzalo himself, and apparently a son of
his, followed Ferdinand III in the great campaign of 1236-48 that gave
Cordova and Seville to Christian Spain and penned up the Moors in the
kingdom of Granada, and his descendants intermarried with some of the
noblest families of the Peninsula and numbered among them soldiers,
magistrates, and Church dignitaries, including at least two
cardinal-archbishops.

Corregidor of Jerez and ancestor of the Mexican and Columbian branches of
the family; and another, Juan, whose son Rodrigo married Dona Leonor de
