My grandmother said that she heard something about a relative marrying an American Indian, or at least was associated with them.
I was keen to find out if there was any truth to this, so it was one of my main goals when researching her ancestry.
It's important to keep in mind that my grandmother is the youngest child of the youngest child. By that I mean her parents were approaching forty when she was born, and her father was also born when his parents were approaching forty. So the generation gaps are much larger than normal. Which meant that even close relatives were distant memories to her.
I did discover that three of her aunts, who were all Glaswegians, married Italian immigrants. But she knew this already, and my grandmother actually has an Italian first name referencing that part of her family. But no American Indian connection was found.
Then I found out she had a cousin who became involved with the film industry, and married an actor who appeared in a couple of silent films. There were photographs, and in one film he portrayed an American Indian!
