虽然是角色相关的东西，但看过电影的表示＜史矛革荒漠＞没有提及这个细节，至少电影版没有，加长版在下不知道。来源是电影杂志，不过还是说一说剧透警告吧。

摘自<Entertainment Weekly>在TheOneRing.N et的节录：
“Youmentioned something that sort of triggered something in my mind, which is ‘Tellme something about her past’ and a lot of people won’t know because it doesn’thave a place in the film anymore. At one point it kind of did, but a part of Tauriel’s backstory isthat she is an orphan. Her parents were killed by orcs. When youunderstand that, you suddenly understand how and why this girl became thelethal killing machine that she is, how she became the head of the elven guard,how she got taken under Thranduil’s wings, and why she’s so passionate aboutfighting the evil that is in Middle Earth.”
渣翻译：
「你提到的东西令我想起点事，就是”说说她(Tauriel)的过去”。很多人不会知道，因为电影没有时间交代。这可以理解，但关於Tauriel的背景出身，其实她是孤儿，她的父母被半兽人杀害。当你意识到这点，你会突然明白这个女孩为何会成为致命的杀人机器，为何会成为精灵卫队的首领，为何Thranduil会这麼重视和保护她，还有她为什麼非常执著於抵抗中土的邪恶势力。」
另外指环王维基也记载：
Her parents were killed by orcs when she was younger and it is hinted that Thranduil looked after her since then.
【她的父母在她更年轻时被半兽人所杀，而有暗示指出瑟大王在那之后照顾她。(可以理解成收养吗?】
所以说桃子为什麼要去追兽人咧。。。为什麼瑟爹审兽人时耐不住想宰了兽人咧。。。。。。至少９０％跟某矮人无关吧！
每位年轻战士背后都有一段悲伤的过去
