Baby Girl Name

My husband and I are expecting our 3rd baby in June. We don't know if it's a girl or a boy yet. We have a boy name picked and are almost set on a girl name. Which middle name do you think sounds best with Violet? If it's a girl, we're naming her after my husband's grandmother who passed away last year. So we're set on Violet (with the nickname Lettie) but we're having a hard time deciding on the middle name! So Lettie Averie or Lettie Brooke? Thanks in advance for any input!!
