You know what. That’s a very good idea. I actually made one for the Montfort family tree (in theory the Montfort family tree since it ends up connecting all the way to Lyra through various ‘by marriage’ relations) a while ago that I think is up to date. Here’s the link, which hopefully works.

But also… if you have any questions regarding how characters might be related please feel free to ask! Often the answer is as simple as ‘I though it would be cool if these two canon characters were siblings/cousins/etc’
