Luna questions

[melissaworcester]

Hi everyone! I am on no-mail here, so if you reply to this please 
leave the subject the same so I can find it, when reading on the web 
site.

I want to write fan fiction about Luna, and I have some questions. I 
returned OoP to the library so I can't look these up and I wonder if 
anyone could tell me:

How old was Luna when her mother died? 

Does it mention or hint at any siblings she has or other members of 
her household (like a grandmother who lives with her and her father, 
etc.)?

Is there any hint of where she lives or whether it's the same 
Lovegood family mentioned at the beginning of GoF, when they meet at 
the portkey to go to the World Cup?

Can someone list some of the strange creatures or other things she 
seems to believe in that Hermione is convinced doesn't exist?

Any help with any of these questions would be greatly appreciated, 
thanks!

Melissa
