No... once again: I abhor Anne Rice's puerile vampire-penny-dreadfuls (the former Anne Rice, I recently discovered). The name 'Lestat de Lioncourt' was not her creation; rather, Anne Rice's French-illiterate larceny. She has no claim to the family name or the origin.
Writing openly, in adolescence I read her first book at the request of a classmate; yet the second release in her 'Vampire Chronicles'... unreadable. I did not finish. A novelized emetic. From a plot summary of the third release, continued mindless insensibility - which describes the author, as well... I could not tolerate the absence of creativity, or her risible (re)vision of the 'vampire'. My opinion, reader, used toilet paper offers a more compelling story.
I am a descendent of Guy de Lioncourt, French composer (1885-1961); and if our genetic resemblance is not obvious, well, perhaps consult your nearest ophthalmologist:
