Lars family
The Lars are a family of moisture farmers on the desert world of Tatooine eking out a humble existence at their homestead on the back-water world.
Cliegg Lars
Cliegg appears in Star Wars: Attack of the Clones. He purchased Shmi Skywalker from Watto and married her. When she was kidnapped by Tusken Raiders he led a rescue effort that resulted in the death of 26 of the 30 humans in the party and the loss of Cliegg's leg. The injury prevented him from organizing any further search attempts and he accepted the thought that she was dead. Anakin Skywalker appears a month later searching for his mother and after killing the Sandpeople who tortured her to the brink of death, brings back her body. Cliegg pays his final respects.
Owen Lars
Owen is Cliegg's son from a former marriage. He is the adoptive father of Luke Skywalker and feels a strong need to protect the young Luke from the evils of the Galaxy and trying to discourage Luke's desire for adventure. Most of all, he doesn't want Luke to follow the path his father took and so he made up a story about Luke's father being a freighter navigator. Owen continuously tries to postpone Luke's application to the Imperial Academy for the same reason.
Beru Whitesun Lars
Beru is Owen's girlfriend in Star Wars: Attack of the Clones and his wife in Star Wars: A New Hope. She serves the role of mother to young Luke after she and Owen adopted their nephew at the end of Star Wars: Revenge of the Sith although it is unknown if she and Owen were married at that time. She tries to be a moderator between Luke's desire to leave Tatooine and Owen's overbearing protection of their nephew, going so far as trying to persuade Owen to allow Luke's application to the academy.
Owen and Beru were killed by Imperial Stormtroopers who had traced a pair of droids to their homestead.
