I found the following passage earlier today in The Best of Trek 8 edited by Walter Irwin and G.B. Love. This is taken from the article, “Some Thoughts” by C.J. Nicastro.
It is important to note that Spock also fits into the Wold-Newton list via his mother, Amanda Grayson. She is the great-great-etc. granddaughter of Richard “Dick” Grayson, who, in the late 1930s, was adopted by millionaire Bruce Wayne. Wayne became police commissioner of Gotham City, and when he died in the late 1970s, Grayson inherited his role as a crimefighter–Batman! So, a tradition of righting wrongs–and a stronger element of emotionalism–exists in Spock’s heritage.
If you’re not familiar with Wold Newtonry, in a sentence it’s an attempt to reconcile the existance of all the major characters of pop-culture and popular fiction as existing in roughly the same universe and, more-or-less, ultimately from the same family lineage. I’m not too well read on Wold Newton, but it is interesting nonetheless. The other prevalent Wold Newton claim with Spock is that he’s a descendant of Sherlock Holmes, which I guess makes sense but I’ve never found that compelling. Again, however, I’m not that well read in Wold Newton.
