Corinna for the girl and Pindar for the boy. This is especially fitting if the K1 is the girl... though I guess it works the other way. Then you can name the DX Plutarch! Corinna was an ancient Greek poet and she taught and became Pindar's Rival. Plutarch was an ancient Greek historian who wrote a lot of essays and is one of the main sources we have on both Corinna and Pindar. Sorry... history major.
