If we go back 200 years or so, I would think a big percentage of Americans today could trace their family history back to some relative that owned slaves.
That was then, this is now.
Not so fast!
Big immigration from Eastern and Southern Europe right before and after WW I. Poles, Slaves, Greeks, Italians etc. If your last name ends in a vowel, good chance that side of the family is clean.
I think I'll file a civil suit for damages inflicted upon my family from Pennsylvania who died freeing some black asses. Where's the repairations for that?
