The Family Trees
NOTE: THIS CHAPTER CONTAINS SPOILERS!Potter Family Tree
Wow, this one took a while. I would like to make a few notes about this tree. I took the liberty of deciding that Dorea Black was the great gran mum, and I think I have left out a few characters such as the Aunt. The reason is that I haven’t a clue where to place her, so I just left her out. I hope that is okay with you.
Now as for ages well:
James Sirius Potter, oldest son of Harry Potter was born in 2005.
Albus Severus Potter, the youngest son of Harry was born in 2006.
Lily Luna Potter was born in 2008 and is the only daughter of Harry and Ginny. She is the youngest in the family.
Teddy, who was not included in the family due to not being a blood relative lives with the Potters, as his father, Remus is dead. I think we all know this by now but I just wanted to add a little note so the poor fellow doesn’t feel left out.
The Weasley Family Tree 
So this is rather short, you’d think that the Weasley family was bigger, but they aren’t. Well they are, but that is only thanks to the Prewetts, who I did separately. Now, when there is a d in the tree, that means that this person has died. Usually the date will be there after words.
The Prewetts
These people are above the Weasley family, just so you know. You’ll notice that Molly’s father was unknown, that is because J.K. Rowling never mentioned his name or what not. I am sorry about this. You’ll also notice that some of the blacks have been included, well they are related just like nearly all the other purebreds.
The Delaclour Family
Ah yes, the mysterious yet beautiful French family from which Fleur came from. The poor girl choose Bill to Marry. It isn’t Bill that she should worry about, as he’s absolutely in love with her, but what about the mother? Molly is fiercely over protective of her kids, don’t you think? Imagine, a vela trying to take one of hers away. Or at least that is what she thinks. This however, is completely untrue as we all know. Anyway, there wasn’t much I could find on them, just this. I hope its good enough.
This is all I’m doing for now. Let me know if you’ve had any troubles understanding the trees. If your looking for the Black Family tree, there are many, all you have to do is look on Google or on Rowling’s site.
Next Chapter: Oh, the woes of time. When did book six take place? How can I change it so that it fits Buffy’s timeline? Is this possible? How old would Harry be when Buffy….
P.S: In case your wondering why I left out Hermione's family, its because everyone of her relatives are unknown. Her mum and dad are dentists but thats all we know. There has been no name given to this day. Sorry, but hey, that gives you a way too create more characters for the Harry Potter world.
Oh, what if Hermione's parents were Willows? Hm, that would be interesting. It would also explain why they left Willow alone so much, don't you think?
