Who are Mrs. Fuji and Mrs. Gas?


Is there any etymological relationship between the -さん suffix in 富士山 or 月山 and
the -さん suffix you put at the end of a person's name? Or are they unrelated?




Totally unrelated.  
山 さん [mountain] is a Chinese word "shān" assimilated in Japanese.  
さん as a honorific suffix is an old さま undergone some phonetical change.  
There are many homophones in Japanese besides that.
