Uruchi Uchiha

Uruchi Uchiha (うちは ウルチ, Uchiha Uruchi) was the wife of Teyaki Uchiha, and used to own a small bakery at the Uchiha compound in Konoha. She used to be one of the many people in the Uchiha clan who encouraged Sasuke to be like his big brother, Itachi. In a short conversation with Sasuke, she does not seem to pay attention to him, not knowing how old he was. She was eventually killed by Itachi (as well as the rest of the Uchiha clan; except for Sasuke who he left alive). Sasuke referred to her as an aunt, and called the man who interrupted in their conversation to save Sasuke from answering, uncle. (Source: Narutopedia) Since she is from the Uchiha clan, she should posses the Sharingan. But this is unknown as she is not using it or mentioned using it.
