Apologies in advance - but you have invited opinion!
This is a Chav name. Why? because it's almost certainly a "made up" name and Chavs like nothing better than to make up their own names or re-arrange the spellings of existing names. Or better still, do both at once! e.g. Chelsey.
Chav: Chardonnay, Chelsey, Brianna, Tyler, Shannon, Coleen, Kayleigh, Shawna; Brogan, Morgan, Brody, Flynn, Tyler, Lee, Wayne, Shane, Ryan, Bradley
Non-Chav: Elizabeth, Catherine, Sophie, Laura, Christine;
Henry, James, Michael, Thomas, Oliver
Sorry but Lyra is a "made up" name. Never heard of it before. Sounds a bit like Lycra.
I would put it in the same sort of name category as Kayla or Kyra. Made up. Chavvy.
