and Many of those 1.6% "Slave owners" were family members buying their family members too.
I am from Pa, where many people would buy "Slaves" not for "slavery" sake but to get around loopholes. If a free man was caught down south with no "Owner" he would often be thrust back into slavery. If someone else(good person, family etc) "Owned" him he could not be taken by a southern slaver. Kinda like a car title, unfortunately.
My Bff's uncle was caretaker for a famous "Quaker meeting house and cemetery" and there was a lot of "Underground railroad" ppl buried there. (we accidentally set it on fire as kids, story 4 another time)
Many "Underground railroad safe houses" "Stops" were in fact "Quaker meeting houses"
The Quakers were vehement abolitionists .
People like Thaddeus Stevens (Tommy lee Jones character in "Lincoln") Purchased "slaves" freedom and are counted in the 1.6%
The late Great , Best defensive lineman ever "REGGIE WHITE" would buy "child slaves" in Africa b4 he died to give them with good homes in the USA much like some slave owners of the past.
