So:
Knowing that:
Flampe is the 36th daugther, 15 years old, and Anana is the 39th with 8 years old
And in the boy's side, Anglais is the 14th year old, 42th son, and the twins Dolce and Drageé are the 45th and 46th with 9 years.
The 13y/o, 12y/o, 11y/o and 10y/o must have been single births, as we still haven't placed the 37th, 38th daughters, and the 43th and 44th sons. Those four, plus the 41th son, Pudding's closer brother by birth order, are the missing ones beyond the long neck twins.
Weird that we don't have a candidate for the 41th, as using Flampe/Anglais as a benchmark, as she was the youngest Charlotte combatant, then that boy should also be around somewhere.
! 01th Husband 50y/o Perospero
02th Husband 49y/o Compote
03th Husband 48y/o Katakuri Daifuku Oven
! Opera and blobs (4th to 9th Sons)
The 2th daugther has to be younger than Katakuri, but older than Cracker.
! 45y/o Cracker (10th son)
! 42y/o Baskarte flaminghair (13th son)
41y/o Nosiette elvishairbeard (15th son)
There is a multiple birth up here
! 35y/o Smoothie (14th girl)
34y/o Saint Marc (22th boy)
! 32y/o winged mohawk Magellan Wanabee (24th son)
! Praline 21th girl unknown age
28y/o Pumpkinface 28th boy
! 26y/o Lola and Chiffon (22th 23th girls)
the 24th daughter must be either the twin of the 25th or here it is the double birth of the year
25y/o Longarm girl 25th girl
! Joconde 27th daugther
! Brownie 32th son
Raisin 33th son
! Between 27y/o and 21y/o there are for sure 7 sons, including Brownie and Raisin.
Between 24y/o and 21y/o there are for sure 3 daugthers, including Joconde, at the very least Raisin must be younger than the 25th daugther, to have the minimum 4 childs born these years.
! 31th husband 20y/o Joscarpone and Mascarpone (29th daughter 34th son)
32th husband 19y/o Yuan
33th husband 18y/o the decuplets
34th husband 17y/o Pudding or 41th
35th husband 16y/o
36th husband 15y/o Flampe
37th husband 14y/o Anglais
38th husband 13y/o
39th husband 12y/o
40th husband 11y/o
41th husband 10y/o
42th husband 09y/o Dolce and Dralge
43th husband 08y/o Anana
I doubt the two births one year siblings are on this side of the equation
