Barbara A. (Sleppy) Drennan, 89, of Springdale, passed away Friday, Nov. 26, 2021. It is with deep sorrow that we announce Barbara's passing. As a registered nurse for over 27 years, and an active member of her local church, Barbara spent her life serving others, and especially enjoyed working with children. She loved working in her yard, attending her flowers and just being outside. Dedicated to her Christian faith, Barbara enjoyed bible study and bible camps and was ever willing to step in and lend a hand wherever she could. A loving and caring wife, mother, grandmother, aunt and friend, Barbara will be missed by all who knew her. She was predeceased by her husband, Richard M. Drennan; her parents, John Sleppy and Mary (Frank) Sleppy; and six siblings. She is survived by her sons, Todd Drennan, of Natrona Heights, Kirk Drennan, of Fayetteville, N.C., and Brad Drennan, of Cheswick; four grandchildren, Walter, Caitlin, William, and Mary Morgan Drennan; and Gwendalyn, the cow, a steadfast sentry of the front yard for over 40 years. A Memorial Service celebrating Barbara's life will be held at 6 p.m. Thursday, Dec. 2, 2021, in the Presbyterian Church, 1401 Pittsburgh St., Cheswick, PA 15024. Barbara will be laid to rest at Greenwood Memorial Park, Lower Burrell.
