Is there a hook available for the Contact "relationship" page that is similar to HOOK_civicrm_summary?   I would like to list derived relations for a contact on the "Relationship" page/tab.

For example: John is a parent of Bob. Bob is a parent of Susan.  So on the relationship screen, I would like to show that John is a grandparent of Susan.  ( Without requiring that someone add the grandparent relationship directly between John and Susan. )    

Another example: Paul is a child of Debbie . Steve is a child of Debbie. I would like to show that Paul is the sibling of Steve.

Hi,

You can also add a custom api "calculatedrelationship_get", that returns the list of contacts that are grandparent of (or sibling or...), and call that from within the template with {crmAPI}
