A: We don't really know what happened to Ankhesenamen. She was alive when Tutankhamen died, but seems to have died before Ay did, four years after Tutankhamen's death. You see, in Ay's tomb, his wife Tey is shown as the Great Royal Wife -- the Queen. If Ankhesenamen, the last carrier of the royal blood, had been alive, Tey could NOT have been the Great Royal Wife. Ankhesenamen may have taken ill, been murdered, committed suicide, or some romantics have suggested that she ran away, and lived out her life elsewhere. This, however, seems unlikely.
As for her tomb, we have found no evidence that she was even burried at all! No shabti or other burial equipment. Nothing. :(

Q: Who were Tutankhamen's parents?
(Ankhesenamen didn't REALLY marry her half-brother, did she?)

A: The question of Tutankhamen's parentage is still up in the air. The main canidates are Amenhotep III & Tiye and Akhenaten & Kiya. I favor the Akhenaten and Kiya scenario. If this is true, yes, Ankhesenamen did marry her half-brother -- but that wasn't seen as taboo in royal families. Full brothers and sisters in ancient Egyptian royal families often married, and sometimes even fathers and daughters. The gods did this, and since the king was a god, why shouldn't he do the same? The average Egyptian, however, did not marry their siblings.

Q: How do you pronounce "Ankhesenpaaten" and "Ankhesenamen?"

A: No one is sure, but in English, our best guess is AHNK-es-en-pa-AH-ten and AHNK-es-en-AH-men.

Q: Hey, wait. I thought it was spelled "Ankhesenamun" or "Ankhesenamon?"

A: The Egyptians had this habit of not writing vowels. For example, what we say as Amun, Amon, or Amen was actually written more like this: I-mn-n. Egyptologists have added vowels to make things easier to pronounce. Any of those spellings are just as valid as the others. I favor the -amen spelling for a couple of reasons:
1) It is used in KMT: A Modern Journal of Ancient Egypt, Nefertiti: Egypt's Sun Queen by Joyce Tyldesley, The Murder of Tutankhamen by Bob Brier and Pharaohs of the Sun: Akhenaten, Nefertiti, Tutankhamen; all recent works.

2) It is common practice to add and 'e' to Egyptian words to make them more pronouncable.

3) It seems to me that if it was a pronounced 'u' sound (ex: Ankh-es-en-ah-mOOn) the Egyptians would have written it. They wrote the u (or w) in Tutankhamen's name (t-w-t or toot), so why not in the name of Amun, Imnn? The 'e' is a softer vowel, so I prefer it. Like I said, all spellings are equally valid -- it's a matter of preference! :)

Q: What happened to all of Ankhesenamen's sisters?

A: Meritaten died shortly before or after Smenkhkare of unknown causes. She would have been in her late teens/early twenties.
Meketaten died somewhere between Year 12 - 14 of Akhenaten, either of plague or during childbirth. She was about 11 or 12.
Nefernefruaten ta-Sherit was still alive when Meketaten died, it seems, because she is shown mourning the loss of her sister. We don't know what happens to her.
Nefernefrure may have died before Meketaten, but again, we just don't know.
Setepenre was quite possibly the first Amarna princess to die, before Meketaten.

If you are getting hung up on some of these Egyptian words or terms used at this site, trying visiting the The Amarna Glossary. One more tool from the helpful folks at Ankhesenamen's Palace! :)
