So I've updated the Charlotte family table I made several months ago with all this new information:
!
As a reminder, many of the ages are taken from the Volume 90 SBS.
I did make a few assumptions while organising this table:
A. Big Mom gives birth about once a year, regardless of character birthdays.
B. Monde is a twin of Amande, Ash and Efire.
C. Broye is a twin of Brulee.
D. Melise has a twin brother, the polka-dotted antler guy.
E. Marble, Myukuru (whom I've romanised as Mukle), and Maple are triplets.
F. Newgo is the youngest of the decuplet brothers.
Despite all this, there are still some uncertainties regarding who's older than whom.
For example, I could easily move Panna and Joconde further up to where we have some empty son slots to fit with the theory that Panna has a twin brother named Cotta.
Without any clues like age or how other siblings refer to them, it's hard to say if, for example, Melise might be older than Bavarois or Snack.
If there's anything I may have missed, feel free to correct me. I'd like this table to be as accurate as possible when the time comes.
Oh, and Dosmarche should be on there somewhere but I'm going to wait until the sons list comes out before I include him.
