Marky Underwood

Mrs. Mary Kathryn "Marky" O'Callaghan Underwood, 82, of Newnan passed away Sunday, June 22, 2025. She was born June 29, 1942 in Atlanta, GA to the late Leland James O'Callaghan and Mary Mees O'Callaghan. Marky grew up in Atlanta, GA and was a 1960 graduate of Northside High School. She received a degree in history from Emory University in 1964, where she was president of Tri Delta sorority. She initially moved from Atlanta to Newnan in 1973. Marky and Delta pilot Ronald Lee Underwood married on June 2, 1985 and continued to raise a combined family of 6 children. Retirement brought a move to beach life at Amelia Island, Florida for 10 years before moving back to Newnan in 2016. Marky was a woman of many talents and interests, including tennis, bridge, music, and, later in life, art. She loved people, as her family and many friends can attest, and had a ready sense of humor, which she modeled after her father L.J. "Jim" O'Callaghan and paternal grandmother Mayma. Marky painted life with a broad brush, refusing to sweat the "small stuff." She brought joy, love, and laughter wherever she went, along with a strong sense of gratitude regardless of life circumstances. Marky was a faithful member of Central Baptist Church, enjoying many facets of church life. She found joy in sharing her love of music as an alto in the choir for many years. She also found joy in service to others as a guardian ad litem and as a volunteer at Central Baptist's Feeding our Friends program. Her greatest joy, however, came from being with her family including her husband Ron Underwood, their 6 children, 14 grandchildren, and 6 great-grandchildren. She was an enthusiastic attendee of graduations, grandparents' days, piano recitals, band concerts, and many sporting events including football, soccer, and volleyball. The memorial service will be on Thursday, July 10, 2025, at 11:00 AM at Central Baptist Church, 14 W. Broad St. Newnan, with Dr. Joel Richardson officiating. The visitation is Wednesday, July 9, 2025, between 5:00 and 7:00 PM at McKoon Funeral Home, 38 Jackson St, Newnan.
