Robert was born on March 12, 1941, in Greenville, Texas to Bill Duncan and Ruth Bench Duncan. He graduated from Greenville High School in 1959 where he had a host of friends. Robert married Carlene Perry on April 26, 1963, in Greenville, Texas. He retired from Raytheon where he worked his way up to Vice President upon retirement. Robert was a member of Lake Fork Baptist Church. In life, Robert enjoyed many things such as hunting, fishing, his many four legged friends over the years, and time with family. His Faith was strong, and he always made God a priority in his life telling everyone about Jesus and looking forward to going home one day to Heaven. We know he misses his "fab 5", his sisters, and all the special friends he leaves behind; however, Robert would always remind us, "It is never goodbye, just see you later in Heaven."
