Nuevo Mexico

Nuevo Mexico is a background planet, mentioned at least three times although never visited, in Poul Anderson's History of Technic Civilization:

Manuel Felipe Gomez y Palomares, an ensign in van Rijn's company, is from Nuevo Mexico;

the Nuevo Mexicans are "...poor and haughty colonists from the far side of Arcturus..." whose customs include great formality and courtesy (David Falkayn: Star Trader, New York, 2010, p. 278);

Fleet Admiral Juan de Jesus Cajal y Palomares and his daughter Luisa are from Nuevo Mexico;

"Luisa had been raised among folk who, if strict out of necessity on their dry world, were rich in honor and bore a hair-trigger pride" (Rise Of The Terran Empire, New York, 2011, p. 471);

Saint John, Hagios Ioannes and the continent of San Juan on Nuevo Mexico are named after the St John who wrote some books of the New Testament.

Only while writing this post have I noticed that the ensign and the Admiral have the same surname. This looks like another of those families that endure through successive periods of the History.
