Viramontes from Zacatecas

I consider other spellings as alternate spellings rather than mis spelllings.

It might be offensive to some people to say their ancestors mis spelled their own names.

For example, it was actually correct to spell Felipe with a "Ph" rather than an "F," before around 1700. That's why the archipelago off the coast of Asia is called the Philippines, but the people are called Filipinos in Spanish and English (and Pilipino in Tagalog, the language of the islands which has no F or Ph sound).

In reality there were many ways of spellings names until the Spanish language was standardized with the change of dynasties in Madrid, from the Hapsburgs who died out, and the Bourbons, who initiated widespread changes throughout the empire.

It was the Bourbons who brought about the metric system by scientific research in what is now Ecuador.

Gradually the old measurements, and coins such as the ocho reales, and two bits, were replaced by decimal based denominations such as the centavo and peso.
