Need help removing completely AI generated person/"artist"

This is Joseph Roy Dixon, he never existed. He is AI generated, the "discography" posted online is all AI generated also, his story is AI generated. I am trying to wipe this off of all the sites it's been blasted onto, which includes ancestry sites, findagrave, etc to make it seem as if he's someone who existed.
