A little family irony

My aunt gave me a family tree that was compiled by one of my distant cousins. It's actually a bit more than a simple genealogical chart, but not much more. More like a chart with notes. There was however one item that caught my eye whilst reading over this.

My Great-Great (followed by four or five more "Greats") Grandfather served with the Georgia Militia who rooted the Cherokees from their homes in this area.

The irony of this comes from the fact that his mother was a full-blooded Cherokee. Some of the people he helped displace had more white blood than he did.
