that is like my Grandmother..she never would talk about my Great grandmother being Native Indian because they tried to hide that fact.
Now they are all dead and NOBODY knows who/what/where etc about our native roots.
----------------------------------
The Grandma who raised me was supposed to be part Indian, but was raised to never, ever mention such a thing in public. And so was I not to ever mention that my Dad's mother was German during WW2, it was well known but never spoken about. I don't much look Indian but pictures of my Mom with her sisters made my one of my Grand Kids comment they looked like a bunch of old Squaws!!!
And my Dad said he was the only guy in the Navy (1918) who had been raised on a farm where the after breakfast and lunch prayers ended with "AMEN, Boys hitch up the team." Surprised him to find that after meal prayers weren't common. (Not that he followed their teaching....)
