Yes, it's complicated... I tend to over-complicate the familial relationships in my stories... you should see the family trees for my MAIN fictional universe...
I forgot to add Rune and Crimson (Clover's twin sister and older brother) to the tree, but they may or may not ever actually get made into dolls although I've been planning them for a while...
As you can see, Clover is a descendant of Tacky's sister and Nerisa's brother... although the only other member of the family who will actually be embodied as a doll is Tacky's brother Jericho. (He's integral to the story of how Marika died.)
