In addition to her parents, Irene was preceded in death by her brother, Robert “Bobo” Lenda; her sister, Phyllis Chidester, and her husband, William and her brother-in-law, Carl Rosenberger. She shared a beautiful life with her beloved husband, Thomas Rosenberger, with whom she celebrated 60 years of marriage: a union defined by steadfast devotion, love, and partnership. In addition to her husband, she is survived by her children, Todd Rosenberger (Denise Trehar) and Lea Rosenberger, her cherished pet, Mia and her step- grandson, Andrew Coplin. She is also survived by her sister-in-law, Norma Rosenberger, her brother-in-law, Jerry (Anna Marie) Rosenberger, her sister-in-law, Roberta Monos, seven nieces, five nephews, ten great-nieces, eight great-nephews, three great-great-nephews, one great great niece, six godchildren, many dear friends, and an extended family in Poland who mourn her loss across the miles.
Irene was of proud Polish heritage, a lineage she cherished deeply. She was a 1961 graduate of Ambridge High School and dedicated many years to her professional career as a meticulous and dependable Payroll Administrator. Her strong work ethic and attention to detail left a lasting impression at several organizations, including Wyckoff Steel, Temporaid Services/Action Personnel, Allegheny Plastics Inc., and KMA Manufacturing, LLC, from which she retired. She was also a woman of deep and unwavering faith who was a devoted member of St. John the Baptist Catholic Church in Monaca. In keeping with her lifelong spirit of generosity and compassion, her final act of kindness was serving as an organ donor.
Friends and family will be received on Wednesday, January 28th from 2-4 P.M. and 6-8 P.M. at Simpson Funeral & Cremation Services, 1119 Washington Avenue, Monaca, who was in charge of her arrangements, and where a prayer service will be held on Thursday, January 29th, at 9:30 A.M., followed by a Mass of Christian Burial at 10 A.M. at St. John the Baptist Church, 1409 Pennsylvania Ave, Monaca. Burial will follow. The family extends their heartfelt gratitude to the compassionate and dedicated staff of the Critical Care Unit at Heritage Valley Hospital for the care and kindness shown to Irene. In lieu of flowers, the family respectfully requests that memorial donations be made in Irene’s honor to St. Vincent de Paul of Monaca, Pennsylvania, continuing her legacy of faith, generosity, and helping those in need.
