Oh, thanks ID. I did read the earlier parts of that thread and remember Nordmann's story of his ancestor. But I hadn't lnked them - hadn't really remembered the context, I suppose.
Probably I should shift this to fit there, but I don't think I could close this one, so it won't matter. My impression of the people who came here is that they didn't deny their Indian ancestry but they played it down a lot and wouldn't discuss it. It wasn't the Indian part that was difficult, I think, so much as the stigma that had been felt as a mixed-race person.
130 people isn't a lot, though other small communities have made their presence felt, but these youngsters were just teenagers and would have been scattered on farms and households, so presumably not able to form an Indian community as such, or join ones already here.
