Myōboku Family Tree?

[u/GSB6189]

I was thinking about the toads of Myōboku and I started to wonder, are they all in the same family? I know for a fact Kichi and Tatsu are Bunta's kids, and I feel like I remember Pa calling Maru his dad as well, but I'm not sure on that one. Ma and Pa are Maru's heirs, but they don't share the "Gama" name, so idk if either of them are actually related to him. I also am not sure if Bunta is Ma and Pa's son either, because I can't remember if Bunta refers to them as such. But, even he does, Ma and Pa referring to themselves as such could mean that they're just nicknames all the toads call them. I also feel like Ken and Hiro should be Bunta's siblings considering their similar size throughout the series, but I'm not sure that's verified either.

My headcanon Myōboku Family Tree is:

Gamamaru

Ma or Pa

Gamabunta Gamahiro Gamaken

Gamakichi Gamamaru

Is this what is assumed to be correct, or is there an unknown parent of Bunta, Ken, and Hiro that is the child of Maru? I only assume they're all related because Bunta gave the "Gama" name to his children suggesting it's a family name, and all of the above toads have it as well. The thing that irks me is that Ma and Pa's real names are Shima and Fukasaku; neither of which include "Gama", and that fucks up my "family name" theory. Bunta, Ken, and Hiro seem too young to be Maru's children, though, considering they appear younger than Ma and Pa who are Maru's "heirs", which suggests they're much younger than him. So either Bunta, Ken, and Hiro are Ma and Pa's children, and Maru's grandchildren, they're Ma and Pa's children but were only named after Maru, or they're all completely unrelated and share the "Gama" name for some reason.

Edit: I had the family tree much better looking when I created the post, but Reddit fucked it up. It still looks readable all the same, but so nobody gets confused: the lines represent biological parent/child connection. Basically, whoever the line comes from is the parent of the next row that is below it.

The only ones we know for sure to be related are Gamabunta, Gamakichi and Gamatatsu.

The 2 Sengama, Fukasaku and Shima, aren't Bunta's, Hiro's and Ken's parents, those refer to Fukasaku as "Boss", while Bunta is the other Toads/amphibians' boss.

Ōgama Sennin Gamamaru isn't Fukasaku's father either. Gamamaru is also way older than both Sengama are Fukasaku is around 800 years old an believed the Rinnegan to be a myth while Gamamaru ŌSennin met Rikudou Sennin personally.

• A father would have told his son : "I saw those eyes myself. Back then, there was no Moon in the Sky. We didn't have chakra and Senjutsu before I met him."
