I just realized why they call her Big Mum, she literally is a big mum. I mean if all those 35 daughters are her personal daughters...well she certainly is a matriarch. I doubt thought we will see all of them or that Oda will elaborate extensively on all of them. That Bonney is one of them, meh. As I said Bonney sailed the complete opposite trajectory you would normally expect.
Lmao!! You know what, even though I mentioned her having all those daughters, her name didn't mean anything to me until you literally just pointed that out. XD lol if she is in fact the biological mother to all those daughters, then her name is just too perfect for that big lady. xd haha
I don't think we'll see all of them either.. unless Oda shows a crowd of them at this wedding/tea party, but either way I HIGHLY doubt we're gonna get any back stories or anything to be elaborated on. Unless it's maybe the one who's supposed to marry Sanji, Lola (If she is indeed her daughter), and then that's basically it.. although that's why I wouldn't mind Bonney being one of her daughters.. because out of all 30 something of them, I would think that at least one of them became somewhat well known, and for Bonney it would be cool cause it would've been on her own. Without sailing under her Mom's name/powerful position.
But like you said though, the history of Bonney (from what was given to us) doesn't really match up or make sense for her to be BM'S daughter. So I agree with you that it doesn't make sense logically. Lol
I just want one of her daughters to be a strong pirate, or even marine, that we've seen in the story before, but just didn't know they were related yet. Until Oda tells us. Lol but we'll just have to wait and see.
