[Harry Potter] How did Muggles in the Middle Ages react to the news that their child was a witch and was being offered an education at a far away castle named Hogwarts?

Hogwarts is about a 1,000 years old and humanity hasn't been kind to witchcraft for most of that.

Likely in the height of Middle Ages and anti-magic hysteria, most muggleborns weren't invited to Hogwarts unless they and their families weren't a threat. What's the point of trying to teach a child that doesn't want to learn and that their parents don't want to give up?

That's in huge part why pure-blood supremacy was able to flourish. It was an accepted thing because for a long time much of the Wizarding World was mostly pureblood. It's only after the hysteria died down that the Wizarding World opened up again and muggleborns are more and more integrated into magical society.
