A re-examination of the first five Ground-Level Events (GLEs) has resulted in identification of characteristics that were not noted at the time of the initial publications. These five events, taken collectively, have not been reproduced by the sun since their occurrence primarily because of their intensity at energies >4 GeV as detected by ionization chambers. While we know that the GLE on 23 February 1956, the largest event to date, was recorded by equatorial cosmic ray detectors, examination of the Huancayo bi-hourly ionization data for the GLEs on 7 March 1942 and 19 November 1949 indicates that these events were also recorded near the equatorial region. In a study of the GLE on 23 February 1956 it was possible to obtain one minute time resolution of the cosmic ray intensity at Huancayo during this event. It should be possible to obtain fine resolution of the timing of the earlier events utilizing the original analog records.
