not all of these children have Spanish ancestors ...
The Aztec and the Mayan descendants all try to call themselves so called “Hispanic” and thus claim Spanish blood...
Yeah and I’m Chinese...
Since the Spaniards that came over to the New World in the 16th-17th century were soldiers and sailors-young, single men-they started interbreeding with the Native American women right away-horndog Hernan Cortez himself led the charge by taking the daughter of a chief who opposed the Aztecs as his mistress to cement that alliance-(she was called La Malinche and later founded/became abbess of a convent)their son is regarded as one of the 1st kids of that mixed ethnicity of Spanish/Native American, born in the New World.
My own ancestors came to Mexico from Spain over 400 years ago, and about 100 years later a bunch of them saddled/packed up for Texas and New Mexico. Since they were just farm/ranch class/peasants and not nobility, they intermarried with peasant class Native Americans and Mestizos from the gitgo-so all of our tribe are Mestizos, even those of us with the Basque look-light skin, light eyes, blonde or red hair and all.
After 500 years, you’d have to look really hard to find either a pure Native American/Indian or a pure Spaniard who was born on the American continent-even though some want to claim to be pure Native or Pure Spanish, the genetic testing says it isn’t so-except for a few tribes in the Amazon Jungle-but they-wisely-don’t seem very interested in paying coyotes to bring their kids to the US illegally...
I used to know an Indian guy, (Native, not from India) who claimed that his grandmother was a Canadian “princess”. LOL.
