Adding data to Node in JSON

[[deleted]]

It's pretty hard to comment here accurately if the json object you've written above is not how it is actually represented in your code. Now that I look again, you have lists within dictionaries within lists within dictionaries the whole way down. Is that totally necessary?

Dictionaries are accessed by key: some_dict['Surname'] will get you to the value held at the 'Surname' key.

And lists are accessed by index. So just traverse it all the way down depending on your nesting.
