Question:

How can I find the Blackfoot Native American symbol for grandchild?

My family geneaology is part of the Blackfoot Tribe. I would like to honor my grandchild with a tattoo of the symbol which means "grandchild." I can't seem to find what I am looking for, if it exists.

Best Answer - Chosen by Asker: Looking for something like that, which I don't think exists, at a genealogy venue wouldn't seem that successful a choice any more than asking for brake shoes at a beauty shop.
