You're playing with words.  There was only one *named* family.  There were multiple families in different countries over years, who do not want their names published. 
 *G&M; 2012 says "several parents from Britain and the United States have told The Globe and Mail that their children consulted Freedomain Radio, then became estranged from their families." and "The college began investigating after two formal complaints, one in 2009 and the other in 2011.".   
 *Guardian 2008 says "The American parents who talk to me do not want their names printed," 
 *G&M; 2008 says "Many relatives are loath to come forward, fearing that going public will further alienate their children."  
 I find it odd you want to separate the named family from the issue of other families, and the complaint, but you wish to link the case of the named family with the unrelated quote by Tucker.  I'm mentioning this because you brought it up, but I'm not pushing for any big changes at the moment.  I just want to clean up the lede for the moment, and the coverage of deFOOing can be left for discussion in the indefinite future.
