How to create a family tree structure of nodes?
I'm assuming you've tried to use the Views tree module (there doesn't seem to be a "trees views" module ...). To my knowledge, that module cannot create a graphical visualisation of a tree structure.

I'd recommend to create such tree structure using Graphviz diagrams, and use the Graphviz Filter module. Some more details about this module (from its project page):


  ... a little filter that treats input text as DOT syntax for Graphviz, converts it using Graphviz tools to the requested format(s) and renders it in HTML. It's useful to quickly create graphs dynamically from within Drupal nodes.


For more information, refer to the Community Documentation about Graphing Modules, which has a list of modules for creating either Static or Dynamic Graph Diagrams.
