I am Cree mostly but I do have Cherokee blood on my father's side. I am more into Cree than Cherokee. In my father's family, they never spoke of what happened during the Trail Tears (not sure If I got the title right as it was a long time ago close to the end of the 1800) that make the Cherokees move from Tennessee and Kentucky to move to Oklahoma. My great grandmother had escaped from her people and hide into the mountains. But she hide her identity too. She did tell her children of her past a little bit. It is really a taboo not to talk about being Cherokee. My grandmother was ashamed and very hurt about that.
As for traditional rites and ceremonies, no, I have never been involved in them. I am not the only one. Few of them like me were never involved in traditional rites or ceremonies. Now we start children from school here in the reservation have rites like naming ceremonies. I have never have any naming ceremony and so are my husband's family and himself too. Never had one. That is sad. We are pretty much a modern Indians here.
