Which Harry Potter Characters Appear in All Seven Books Only to Die In Book Seven?

Question

Which Harry Potter characters appear in all seven books, only to die in book seven? [MAJOR SPOILERS/CHARACTER DEATHS]

I can go either way on

Harry,

depending on your interpretation of the King's Cross chapter in Deathly Hallows.

Some feel he died; other believe it was more along the lines of a near-death experience. I'll accept either interpretation.

• I'm not requesting this, but just as an FYI: It's fun to try and answer questions like this from memory before hitting up canon.
• This is not a list question, as there is a finite number of characters who fit the question's criteria.

★ I'm looking for a canon-based answer (the seven Harry Potter novels, the three supplemental books, J.K. Rowling interviews, and Pottermore) and do not prefer an answer from either the HP Wikia or the Wikipedia.

_{NOTE: A few months ago I got an email from a fellow SFF.se user about the Harry Potter questions on the site. Now, I cannot find her email :/ She asked me this question as a personal challenge and I put it onto the back burner, but today I decided I would post it here and see if the user who emailed me will comment so I can fully credit her for the question.}

Answer 1

Yes 100%:

• Fred Weasley
• Hedwig
• Severus Snape
• Vincent Crabbe

Yes if you count being mentioned in a book without being an active character:

• Peter Pettigrew
  Appeared first as Scabbers, only got a flashback in HP5.
• Tom Riddle aka Lord Voldemort
  This one is a bit iffy, as he did not appear as an acting character in HP3, and only appeared as a Horcrux/Tom in HP2.

Maybe (You can lawyer that they did appear, were implied, or whether they died):

• Harry Potter (duh)
  It's disputed whether he died in DH in the first place.

• Lavender Brown
  She clearly died in the movie but not 100% clear if she was merely severely injured in the book. All we get is:

  “NO!” shrieked Hermione, and with a deafening blast from her wand, Fenrir Greyback was thrown backward from the feebly struggling body of Lavender Brown.

  We know that JKR had a fairly big input into the movies, so presumably she was on board with a major items like who among recurring characters died.

• Bloody Baron (As Slytherin Ghost) [ Did not appear in HP3 ]

• Helena Ravenclaw (as Ravenclaw Ghost) [ Did not appear in HP3/HP4 ]
  Both ghosts didn't actually die in Year 7,
  ... but their death was first described in Deathly Hallows.
  Also, they weren't mentioned in 1 or 2 books explicitly,
  ... but it's assumed they still were house ghosts in Years 3 and 4.

• Bathilda Bagshot (as author of "History of Magic" textbook).
  The class wasn't even mentioned in HP6
  ... but presumably taught
  and the textbook wasn't named after HP1,
  ... but presumed to be used in all years (no canon yea/nay).

Runner-ups:

• Colin Creevey
  First appeared in HP2, was in every book since.

Answer 2

I was the one who proposed the trivia question to Slytherincess. The exact wording of the question is:

What characters appeared ALIVE in each of the seven books, but at the end of the seventh book are dead? This wording would exclude ghosts, mentions (anecdotes told by other characters), and appearances in photos/portraits (not alive).

My answers are:

Snape
Crabbe
Fred Weasley
Hedwig the Owl

I considered Lavender Brown, but it wasn't explicitly stated that she died (in the book). Peter Pettigrew/Scabbers didn't appear "alive" in book 5.
