James Royce Dunn's Obituary
James Royce Dunn, age 91, peacefully passed away on July 21, 2026, in Mandeville, Louisiana.
Born in Quanah, Texas, on August 25, 1934, Royce was the son of the late Clarence Edward Dunn and Nova Anna Wilson Dunn. He grew up in Quanah and was preceded in death by his beloved siblings Glyndol "Glenn" Dunn, Harold Dunn, and Katherine "Bea" Dhooge.
Royce graduated from Quanah High School and Texas Tech University. He married Margaret Lilyan Murphy Dunn Hatcher, who predeceased him, and together they had five children, Kevin Michael Dunn, Beverly Gail Dunn Davis, Gregory Scott Dunn, and Rebecca Lynn Dunn Pratt, who survive him, and James Kerry Dunn, who passed away as an infant.
In 1956 he went to work for The Texas Company (later Texaco) as a geophysicist, and except for two years in the United States Army, he would spend his entire career there. He had a long list of job titles there and belonged to the American Association of Petroleum Geologists. He retired from Texaco after a long and stellar career.
He married Gussie H. Dunn and together they raised her three children by a previous marriage. He was preceded in death by his beloved Gussie and her children, Leroy Lloyd Carney, Jr. and Donna Breaux, and is survived by Paula McCabe, who lovingly cared for him in his later years, particularly after the passing of her mother. Royce leaves behind a large, blended family of grandchildren and great-grandchildren.
Royce and Gussie were both avid golfers. Their beautiful sunroom overlooked a water feature and green at the Beau Chene Country Club. They were both active in bridge circles and sang in the church choir, even performing at Carnegie Hall.
A service celebrating Royce’s life and legacy will be held on Friday, August 7, 2026 at 11 AM at St. Timothy on the North Shore, located at 335 Asbury Dr, Mandeville, LA. The family will receive friends for visitation starting at 10 AM.
