Miley Cyrus' family are a noteworthy and interesting bunch.

Her mother - Leticia Jean "Tish" Cyrus - has a satanic tattoo: https://img.buzzfeed.com/buzzfeed-static/static/enhanced/webdr06/2013/9/17/13/enhanced-buzz-14873-1379437819-40.jpg?no-auto

Her grandfather worked with Alan Greenspan (Greenspan was heavily responsible for the 2008 financial crisis - appointed to five consecutive terms as the Fed's chairman): https://en.wikipedia.org/wiki/Ron_Cyrus

She has an obsession with pizza: http://www.j-14.com/posts/10-times-miley-cyrus-pizza-obsession-was-out-of-control-50349/photos/miley-cyrus-pizza-1-75907#photo-anchor

I don't know how common this is (not at all common where I'm from) - but they have a Cyrus Family Cemetery: https://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=13498455 https://www.findagrave.com/cgi-bin/fg.cgi?page=cr&GRid=13498455&CRid=1974242&

Is the Cyrus bloodline something special?

I'm sure there's way more to this than what I've found already.
