That looks like a ceremonial beard... I remember reading that Maori women had ceremonial beards after they had given birth to several sons. I wasn't aware that any Native Americans did anything similar.
I've read about the girl from "Life among the Indians" but never seen her. Interesting.
A Maori woman with chin tattoo, like I was thinking of:
They think Olive Oatman may have been taken by the Yavapai, like this lady:
The hundred and eleven is coming back in tribe. It was a marker of status around these parts, and depending on the width, location, spacing and darkness conveyed what tribe, what clan and what position - like first wife, or second wife. This is my cousin with a modern one - Hupa.
The Blue Tattoo is the biography of Olivia Oatman, quite a good read if you can find a copy! She was fully assimilated into Mojave society - hence the important tattoo - then was taken back into white society, not entirely of her own will. Very good bio - just now finally remembered the name of it. Many of these white women captives, especially those taken as children, were not very happy once returned to 'their own' world. It's an interesting corner of race and racism that remains dark even now.
