Silly Question, but what letter(s) are the most common for your system’s names?

I’ve always just been curious about this, as we tend to keep spreadsheets and stuff (love my little informations) so we realized we have strong connections to one or more letters! We have 10 Cs, and 7 Ms but everything else is pretty equally spread! We don’t have any Os, Qs, Us, Xs or Ys! What about you all? ETA: our original name started with C, so maybe that’s why! Anyone else seem to have more of their ‘original’ initial?
