Mane 6 Applejack = Jacqueline Delanie Appleton IV (It is 4th gen and as far as I know there's been an Applejack in each, hence Applejack the 4th. Also DElanie because it fits a farmer's daughter.) Rarity = Veronica Jemima Belle (Veronica because I feel it fits her. An elegant name for an elegant mare. Jemima because it shortens to Jem. Nuff said there.) Pinkie Pie = Minnie Diane Pie (Minnie as a play on Mena, the rest just her actual name) Rainbow = Raine Danger Dashington (Danger is her middle name. Raine Dashington from which Rainbow Dash comes.) Fluttershy = LaFayette Theresa Shay (Think about it Faye Ther Shay and her shy nature hence her nickname.) Twilight = Tara Velvet Parker (Tara for her voice actor, Velvet for her mother, Parker as the closest rhyme I could get to sparkle as a real name.) CMC Apple Bloom = Abigail Bethany Appleton (I went for the A.B. initials theme here. Abigial shortens to Abbie = AB and with her middle name her initials are again AB.) Sweetie Belle = Samantha Taylor Belle (another initials theme here. S.T. Belle) Scootaloo = Lucy Patricia Scott (Lucy Scott to get her nickname if you reverse it. PAtricia is the feminine of Peter in honor of her voice actor's last name of Peters) Royal Sisters Celestia = Celeste Lauren Faust (the Fausticorn decreed I name her daughter in her honor.) Luna = Selene Carrigan Faust (Selene and Luna are Greek and Roman versions of the same moon goddess. Carrigan is the closest to a feminine of Craig, Fausticorn's husband.)
