James Kirk's middle name was never expanded beyond "T." in the original episodes. However, in one of the Filmation animated episodes ("BEM," written by David Gerrold), the "T." was revealed to be "Tiberius." His brother's full name was George Samuel Kirk. In "What Are Little Girls Made Of?", the android duplicate said to him "Only you call him 'Sam'."
