No wizard will have heard of her.

Most of these people were dead by the time Taylor Swift started making music. Her first album was in 2006, her mainstream crossover was in 2008, and it wasn't until about 2012 that she crossed over into the UK. The only one of these who might have been alive for any of that is Lucius, who would never willingly expose himself to Muggle culture.

I think Rose, Hermione and Ron’s daughter would be a Swiftie and I went to the eras tour in Vegas :)

Lucius 100%
