I have a buddy whose wife is of Latino stock. Darker skin, wavy hair, Latino surname before they were married, speaks Spanish, wouldn't look out of place if she were living in Cuba or somewhere in Mexico. Just for shits and giggles they did a DNA ancestry thing for their family last year. Her results? Majority central European in her background. Apparently the Latino thing was just from the last couple generations or something. Cultural heritage is a hell of a lot different than genetics - just look at Louis C.K. Dude is white AF, grew up in Mexico with Mexican parents. There's no way in hell you can judge someone's racial background and ethnicity by just looking at them.
