I’ve done some fairly extensive geneology research on my family, and there are several slave owners in my ancestry. That being said, I don’t owe anyone a damned thing.
Same here. To find any slave owners in my ancestry I had to go back 200 years. They were in Kentucky (a non-Confederate state). To find slave owners in my wife's ancestry I had to go back 175 years. They were in South Carolina.
Unless your ancestors all immigrated here after the Civil War, chances are that there are slave owners in your ancestry.
