Claire Kinney born October 17 1967 is the daughter of Jack and Joanne Kinney and older sister to Brian Kinney. She is a divorced single mother to two sons. In one episode it suggests that only she and Joanne knew about Brian's sexual orientation; however, before Jack passes away from cancer his son pays him a visit and reveals he is indeed gay. Surprised by this, he responds: ''you picked a hell of a time to tell me you're a fairy" and Brian leaves. Later, Jack stops by his son's loft to bring him a picture of him and Brian as a baby to make amends; at first Brian is not impressed but eventually gives in and introduces Jack to his grandson Gus.
Unlike Brian, Claire seemed to have a better relationship with their father, showing great sadness and emotion during the funeral. It's not clear, but earlier Brian confessed to Michael their father couldn't stand his sister - much like her husband, it is unknown whether or not this is true. He is known as being alcoholic during their childhood. In a memory shared after the service of (his and Michael's youth) suggested he was proud of his son for winning a bowling match and the three jumped up and down and hugged. But the truth was his father came back from the bar just as they won and saw them hugging and asked "what are you - queer?" and he ran off.
When Claire suggested everyone share memories of her father, Brian referred to a memory from before he was born when his father took their mother to a nice dinner then told her she was gonna get rid of him because he didn't want another another child surprising the guests.
In one episode Brian's sister unexpectedly drops by his work and asks him to watch her oldest son, telling him her younger son broke his arm during a soccer game and had to go to the emergency room. He is seen as a spoiled brat, stealing from Brian while he was in the shower. When he is caught red-handed going through his wallet, his nephew explains he was told you never gave the family a red cent. After exchanging words, Brian dunks his head in the toilet - something he'd later regret.
Later that night Brian was coming home from Babylon with a guest to entertain, but as they descended off the elevator, Brian is arrested. His nephew falsely accused him of molestation, insisting he inappropriately touched him. A few days later, Justin, goes to the arcade to confront Brian's nephew to get the truth. There he sees the nephew wearing a bracelet that Brian got from Mexico and attempts to get a better look.
Later Brian, Justin, Deb and Detective Horvath stop by to question his story and he confesses to lying about being molested, insisting his uncle was a "fag" and deserved to die.
After this Claire is not seen or mentioned again on the show.
