No proof as of yet any American Indian in my family but my ancestors look like American Indian. All my granddads brothers and sisters had dark skin and dark eyes. My granddad has light skin and blue eyes. He had 12 brothers and sisters. So 1 in 13 ended up with blue eyes light skin in his family. Interesting.....
Supposedly my former MIL has a rare eye disease that is only found in Seminole Indians. Never heard anything about it outside their family so I take it with a grain of salt.
...but there was this Indian milk-wagon driver in the town.
