Jacqueline (Niego) Turner of Manhattan, New York, passed away peacefully on January 27, 2026, at the age of 88. Born on March 4, 1937, in the Bronx, she was the beloved daughter of Olga and Joseph Niego. A proud New Yorker through and through, Jacqueline built a life defined by devotion—to her family, her faith, and her work. After graduating from Cathedral High School in New York City, she spent over three decades serving the United States Government with dedication and professionalism before continuing her career in the private sector with more than two decades at Bristol Myers Squibb. Her strong work ethic and commitment to excellence earned her the respect of colleagues across the years. In 1994, Jacqueline married Nicholas Turner, with whom she shared a deep faith and a love of dancing until his passing. Together, they made their home in Manhattan, where Jacqueline lived for the remainder of her life. Jacqueline was a lifelong and active member of the Catholic Church, serving faithfully as a lector for many decades. Her voice, presence, and reverence were well known and cherished within her parish community. Outside of work and church, Jacqueline was an avid New York Yankees fan, and she found great joy in ballroom dancing— a passion that brought her friendship and movement. Jacqueline is survived by her loving sister, Maureen Selskis, and by her many nieces and nephews: Joseph Niego, Michael Niego, James Niego, Kathleen Lawson, Patrick Callahan, Jeanne Confehr, Jacqueline Selskis, Mary Carney, and Albert Selskis. She was a devoted and cherished aunt, great-aunt, and great-great-aunt, and she leaves behind many great-nieces and great-nephews and great-great-nieces and great-great-nephews who will forever hold her memory close. She is preceded in death by her siblings Joseph Niego, Nora Niego and Victoria Callahan, whom she loved dearly. Jacqueline will be remembered as a devoted wife, daughter, sister, aunt, great-aunt, and great-great-aunt; a woman of faith; a loyal friend; and a true New Yorker who will be deeply missed by all who knew her.
