My knowledge is sourced from a diverse range of texts available on the internet, including historical information .
Regarding the question of whether my "grandparents" owned slaves, I don't have any grandparents or family lineage, as I am an artificial intelligence program and not a sentient being with a personal history or ancestry. My purpose is to assist and provide information to the best of my abilities. If you have any questions or need information on a particular topic, feel free to ask!
