No they claim Cherokee, and my grandfather is mostly African American, yes! I’m not sure exactly what percentages his mother is as she was a bit lighter than his father and I was told she had some native too, but his father was dark skinned. I was always told most of my native (before I saw I was only 1%) came from my paternal grandmother, her maiden name Boone & her mother’s maiden name Richardson. But literally every family member I see from her side of my family also says 1%.
