Eugene Claudius Kirk

Eugene Claudius Kirk was a Human male in the 22nd century. With Majorie Wimpole he had three children; George Samuel Kirk, James T. Kirk (the famous starship commander), and Michele Suzanne Kirk.

In a 2174 interview with NBC-TV, Majorie noted that James Kirk was much like his father in his popularity with women. 

Background
In the interview transcript Majorie Wimpole refers to Eugene in the past tense; the source does not specify what has become of him, or the status of their relationship at any time. If Eugene lived with his family he resided in the Farside Base, on the dark-side of Luna.

The character of Eugene, the dates (given as a century earlier than the contemporary interpretation of Star Trek history), and many other facts in Star Trek II Biographies point to it being in a radically different continuity to most other sources. Later works (starting in 1982 in the novel Enterprise: The First Adventure) established George Samuel Kirk, Sr. as the father of James T. Kirk, which was canonised in the 2009 movie. Other alternative Kirk fathers include; Benjamin Kirk, from the Gold Key Comics Psycho-File; and George Joseph Kirk, from the novel Academy: Collision Course.
