You are likely quite correct that the road in question was named for General Coppinger, as he was stationed at Fort Gibson for a time. A native of Cork, Ireland, J.J. Coppinger was highly decorated for his bravery as a Captain in the Irish Battalion, or Battalion of St. Patrick, in the Papal Army. He defended the gateway of La Rocca, the citadel overlooking Spoleto. His commission in the US Army was part of an effort by Secretary of State Seward to enlist experienced foreign officers into the Union forces, and Coppinger confirmed this trust in the Civil War. His grave, a Celtic Cross, is in Arlington Cemetery on the ridge near the Custis-Lee Mansion.
