How can I delete an Empty with it's dependent objects? Hi I'm hoping someone can help me.

I'm running Blender 2.82 on Windows 10 with a 3.10 GHz 4 core processor and 16 gig of RAM. 

When I delete an Empty (with multiple objects within it) the dependent objects (I think children is the proper term?) remain in the scene, but are transformed to astronomical sizes - 1000's of meters instead of mm.

I seem to have to delete each object individually, which takes forever.
Is there a way of deleting the empty along with it's dependent objects at the same time?

Having read the posts on this site, I've made sure that I'm in Object Mode before I try deleting anything.
Select your parent object then go to Select > Select grouped (shortcut  Shift  +  G ) and choose "Children". That will select every children and their children and so on. Then you can delete them like any other object.
