President George Washington, POTUS 1, is my 6th Great Uncle. I am related via his brother John Augustine Washington. But I still have fond affection for George, in fact I keep a picture of him in my wallet. But seriously now, he is my Uncle, and the only one I can thank, outside of my mother's roots, would be DNA testing and WikiTree.
Pretty cool to have a SAR ancestor whos brother was General of the Army, and then Commander in Chief.
