    Wait, if she identifies with her 1/32 Belgian, shouldn’t her ethnicity only say Belgian??? I also noticed the musician Jimmy Hendrix it says African American, but he was if Irish descent and identified with his Irish roots.

    • madman says:

      Why would we ignore the 31/32 or her ancestry just because she feels most strongly for her 1/32 Belgian roots?

      • MissMaria says:

        @Madman, because if she identifies with her Belgian ancestry, then we should only acknowledge and list her ancestry as Belgian, since the Belgian would be what she predominantly and only is, since she identifies as that

          When it is known how much of someone is, particularly on more recently added pages, we add the fractions. You are not going to win this argument.

        • madman says:

          I know you’re trolling, but she’s neither of her ethnicities, she’s American. As for identification, she identifies with her Irish and Scottish roots and might not even know she’s part Belgian, so your comment is redundant from the beginning. But there’s no reason to ignore the parts she doesn’t identify with. Unless you have one.

          • MissMaria says:

            @Madman, I’m not trolling. I’m curious, that when there is no record of someone saying they are if Irish, Russian, etc. Why don’t you guys put that down as their ethnicity just because there is no record?

          • madman says:

            Cause we don’t wanna write something that’s not true. If there’s a record, it’s documented. Sometimes, when a statement is believable, we put it down. And if it’s proven false, it’s changed.

    her music is terrible.

    Is Edith May Shaw (1930-1987) her maternal grandmother? She was the wife of Bill Baird according to ancestry trees, but I can’t figure out when (and if) they married. She married John Bradley in 1949, and he died in 1953. SSI only notes her as having last names Shaw and Bradley.
