I was reading some Harlan Ellison essays, and he mentioned that Manson named his child Valentine Michael Smith, because Manson adored Heinlein’s Stranger in a Strange Land… Whatever happened to Manson’s boy? Anyone know?
I had read (cause I’m doing some searching to find an answer to your question) that Manson patterned his life after that character - saw his son referred to on one web page as Charles, Jr.
There’s an extensive interview with Manson at the above website - if you feel like taking the time to slog through all that you might be able to find an answer, but I can’t give you anything specific, and should probably be doing something productive for my employer right now I suppose.
Sorry I couldn’t be of any help.
According to Biography.com, Manson had two sons: Charles Manson, Jr. and Charles Luther Manson.
Oops, I was trying to link directly to the Charles Manson entry and didn’t even notice it was a cgi script. Try this link instead.
