I am trying to create a family tree. I have a use case where there are 10 nodes in one family named family A and 5 nodes in another family name family B. Suppose one node from family A makes a request to a node in family B. I want to establish every possible relationship among both the families. How can that be achieved?

Can you elaborate?  
I'm not sure I understand what problems you are facing.

How is your data model at the moment?
