I think our uncle and his entire family disappeared. Then our dad that is technically Tree's biological father, her mother and her baby brother. Tree's a "vortex" baby in that she was born here.
The rest of us are from alternate realities where our dad was with our moms. And the dad we have here is not any of those versions.
Let's see... Kyoko is our sister with Toshiko. Daddy here married her. Fred and Tyler are the twins that a version of Daddy had with the Doctor and Rose Tyler. That is really confusing at times because they are related via DNA to all three. Probably the TARDIS' influenced. I am one of triplets that Daddy had with Sarah Jane Smith. I was originally here with my sister and brother when we were kids, but then we were thrust out of vortex world and when I was brought back, I was an adult and without my siblings, Holly and Josh.
