I think you know that only BranchGroups can be added or deleted from a live
scene graph, which is why you want the parent of the TG.

How are you getting the reference to the TransformGroup?
If it is using picking, you can set the ENABLE_PICK_REPORTING capablity on
the BranchGroup so that it gets reported in the SceneGraphPath.
Otherwise, you are right that you'll need to have a mapping between your TG's
and their parent BG's. You might want to just subclass TransformGroup and
add a field which holds the parent.
J3D doesn't allow you get the parent of a live scene graph to allow J3D to
optimize the scene graph, but it seems like a ALLOW_PARENT_READ capability
might be useful.
