Millard F. Haire plaque

Born 1850, died 1863. Opposite the headstone, this plaque says it was placed by descendents of Millard Haire. The stone is placed with the more well-known graves of William and David Shelton, who lived in NC but enlisted with the Union and were killed by Confederate troops as they made their way home. I wonder if the Sheltons were Millard's older brother and uncle.
