Hello Fellow Listers: We just returned from a drive through the mountains in and around the 3 Square Hollow area of Cumberland County. Along the north side of the 3 Square Hollow Rd. (on top of the mountain) there was just placed a new monument for the memorial of 3 fellows who died in a cargo plane crash in October 1956. One of the fellows' name was Marvin SEIGLER (ZEIGLER). We had never heard of a plane crash in this area before. Would anyone know any information about this crash? THANKS! Donna
