Of Chicago, IL on Thursday, March 15, 2018. Beloved daughter of Marion (Billante) O'Neil and the late Regis O'Neil; loving sister of Michael (Lauren) O'Neil of Medina, MN; cherished aunt to Emma, Abigail, Mackenzie, and the late Zachary O'Neil; and granddaughter to the late Leonard and Margaret Billante and the late Leo and Mildred Wallisch. Nina was loved by many friends in Pittsburgh, Washington, D.C., Chicago, Los Angeles and beyond. She was an avid reader and scholar who loved singing, theatre, yoga, and most of all being an auntie to her beautiful nieces. Her passion and optimism will be missed by all those that loved her. Family and friends may call at WILLIAM SLATER II FUNERAL SERVICE, 1650 Greentree Rd., Scott Twp. 15220 (412-563-2800), Thursday 2-4 p.m. and 6-8 p.m. Mass of Christian Burial Friday at 10 a.m. in SS. Simon and Jude Church. In lieu of flowers, please consider making a donation to the Children's Heart Foundation in her memory. Nina's beloved father and nephew were taken too soon from heart-related complications and she loved searching for hearts in everyday life as a sign of their love.
