yess!! Robin has one that's in the works right now; it's gonna need updates in the future (more characters, replacing temp icons etc) but the current version shows most of the more important members of his family ^_^
Did anyone else make a family tree of their ocs? I love to see such things, they give impression of a well thought lore, especially when there's a lot of generations! Show them here if you want; no matter if they're drawn or made in family tree generators
personally I did A LOT, but most of them are super chaotic; I have a poorly made Ariamon's family tree (there was a version made in familyecho as well)
and this little silly family tree of these siblings
I have some drawn ones but I mainly use this site to make them!
