Someone who died in 1964 was technically a slave, but not yet old enough to function as a slave. Real slaves were mostly dead by 1940, the few who remained are outliers

Do you understand how that’s really beside the point? Moreover babies being born into slavery served the slave system just as much as a grown man slaving in a field. Slave is a legal status in a system, not a job title. A baby born into slavery is a real slave, not a fake slave.

  Either George, who enslaved her mother, or his brother, Dr. Fabius Haywood, who enslaved her older brothers, Rufus and Andrew,[3] was probably Anna's father

So Anna came into existence because her mother was raped by a man who legally owned her as property. And that was recent enough that Anna lived to witness Gilligan’s Island.

And anyway, she was still a slave until she was six and served her masters as a domestic house servant. When you were six you were probably being educated to read and write and do math.

You guys are so quick with your “well ackshually” that you’re missing the point which is very simple and has been restated by other posters.
