How do I set up a Drupal view with two relationships?
I found my answer at Multiple Node Relationships?

The answer is to go to the Relationships section and add two relationships, each for your node references. You'll find them under the 'Content' group. When adding the second relationship, select it to use the first relationship so that they chain. That will get you &quot;base&quot; node being the lowest level child, the first relationship is that node's parent, and the second relationship is the grandparent.
Then, add the Node: title field 3 times. Set 1 to use no relationship, 1 to use the first relationship, and 1 to use the second. Preview your view. That should get you the basis for what you want. Add sorts, filters and other fields to taste.
