Forum:SH:Conflicting sources regarding Queen Breha: need community advice

I've had a brief disscussion with Rokkur Shen on the talk page of Breha Organa's article regarding the conflicting sources on the Queen's fate. I suppose everybody knows what the problem is. Many sources portrayed Bail Organa as a single parent rearing his adopted daughter with the help of his sisters, but Star Wars 53 implies that she only died with the destruction of Alderaan in 0 BBY. Let me summarize the facts: The question is: should we dismiss that statement from The Last Gift From Alderaan as outdated canon or should we consider that a primary source actually prevails over an encyclopedia? We all know that TCSWE has been wrong indeed in several occasions (calling Tanbris "Trabinis," stating that Rosh Penin died at the hands of Alora etc.) I intend to bring Breha's article to status some day, so I need to know what the community thinks I should do: should the date of death (0 BBY in the destruction of Alderaan be removed altogether)? --LelalMekha (talk) 11:46, April 1, 2013 (UTC)
 * In Star Wars 53: The Last Gift From Alderaan, Princess Leia mused on her father's last moments before the destruction of Alderaan: "It was night in our palace—were you awake or asleep, with Mother... or alone?"
 * In The Complete Star Wars Encyclopedia, Vol. III, p. 111 ("Royal House of Alderaan"), it is said that "With the passing of Queen Breha and the retirement of Bail Organa, their adopted daughter, Princess Leia Organa, became the best-known figure from the royal family in galactic politics." The wording suggests that Breha died at some point before Bail Organa's senatorial career ended (in ]]1 BBY]]).
 * According to Children of the Jedi, Star Wars Journal: Captive to Evil and The Princess Leia Diaries, Leia grew up without a mother. She was reared by her father and her three aunts Rouge, Cellyand Tia Organa. Similarly, the the defunct Star Wars Kids segment of StarWars.com clearly referred to Bail Organa as a single parent.
 * In in Timothy Zahn's novel Scoundrels, Breha was shown to be still alive around 7 BBY.
