Answer by taking a quote from the following article:

Marion Gordon "Pat" Robertson (born March 22, 1930) is an American media mogul, executive chairman, politician, and former Southern Baptist minister who advocates a conservative Christian ideology. He presently serves as chancellor and CEO of Regent University and chairman of the Christian Broadcasting Network. Spanning over five decades, Robertson has a career as the founder of several major organizations and corporations as well as a university: The Christian Broadcasting Network (CBN), the International Family Entertainment Inc. (ABC Family Channel), Regent University, the American Center for Law & Justice (ACLJ), the Founders Inn and Conference Center, the Christian Coalition, an L-1011 Flying Hospital, Operation Blessing International Relief and Development Corporation, and CBN Asia. He is a best-selling author and the host of The 700 Club, a Christian News and TV program broadcast live weekdays on Freeform (formerly ABC Family) via satellite from CBN studios, as well as on channels throughout the United States, and on CBN network affiliates worldwide.

Marion Gordon Robertson was born on March 22, 1930, in Lexington, Virginia, into a prominent political family, the youngest of two sons. His parents were Absalom Willis Robertson (1887-1971), a conservative Democratic United States Senator, and his wife Gladys Churchill (nee Willis; 1897-1968), was a housewife and a musician. He met Adelia "Dede" Elmer (born December 3, 1927 in Columbus, Ohio), a fashion model and beauty queen in the Miss Ohio State contest, who was studying for her masters in Nursing at Yale University. She was also a nursing student at Ohio State University in Columbus, Ohio. They were married on August 26, 1954, and they were both on the path of economic success. His family includes four children, among them Gordon P. Robertson and Tim Robertson and, as of mid-2016, 14 grandchildren and 7 great-grandchildren.  At a young age, Robertson was nicknamed Pat by his six-year-old brother, Willis Robertson, Jr., who enjoyed patting him on the cheeks when he was a baby while saying "pat, pat, pat". As he got older, Robertson thought about which first name he would like people to use. He considered "Marion" to be effeminate, and "M. Gordon" to be affected, so he opted for his childhood nickname "Pat". His strong awareness for the importance of names in the creation of a public image showed itself again during his presidential run when he threatened to sue NBC news for calling him a "television evangelist", which later became "televangelist", at a time when Jimmy Swaggart and Jim Bakker were objects of scandal.  On April 2, 2015, fellow televangelist, Robert H. Schuller died after a two-year battle with esophageal cancer. Robertson released a statement through CBN News.com: "I am saddened by the passing of my dear friend, Robert Schuller, the Founding Pastor of Crystal Cathedral in Garden Grove, California. Robert Schuller set the dimensions for Twentieth Century Christian positive thinking and optimistic action. He is now with the Lord in Heaven, but his legacy on earth will long remain."  In August 2017, Robertson was hospitalized after sustaining minor injuries from a horseback riding incident.  On February 21, 2018, another fellow televangelist, Billy Graham died of complications of Parkinson's disease. Robertson released a statement through CBN News.com: "I join with millions of my fellow Christians in mourning the passing of Billy Graham. Without question, Billy was the preeminent voice of evangelical Christianity in America--an advisor to Presidents, and a spiritual guide to the multitudes who attended his crusades all over the world." He then added: "Billy has been a dear friend of mine personally and I will miss him. He is now with our heavenly Father, well and happy, and joined forever with his dear wife, Ruth. I extend my profound sympathy to Franklin, to Anne Graham Lotz, and to Billy's other children who are continuing his legacy throughout the world."

Gladys Churchill (nee Willis; 1897-1968), was a housewife and a musician.
