In canon, is it established that

grandparents, or was it her parents? 
I'm fairly certain it is her grandparents, 
but for the life of me I cannot find the 
reference. Thanks in advance for any 
replies. 

I reply:
The only passage I can recall that explicitly mentions the Bones 
family is in PS/SS, Ch.4, 55/56 (I'm using the US paperback.) Hagrid 
is explaining to Harry about Voldemort's reign of terror, upon their 
first meeting:

"...No one ever lived after he decided to kill 'em, no one except 
you, an' he'd killed some o' the best witches an' wizards of the 
age - the McKinnons, the Bones, the Prewetts - an' you were only a 
baby, an' you lived."

I can't find a specific reference to how (or even if) the Susan 
Bones in Hufflepuff of Harry's year is actually related to the Bones 
family that Hagrid mentions in that passage.
