Since the id is not unique and useless, you can ignore it.

You could parse through the json and create a list beforehand which has all the information. As you loop through each name, add it to an existing country or create a new country (As Ajay said you might want to check for duplicate entries by checking all values).

names["America"].Add (new person ("robert", 22) );
names["America"].Add (new person ("albert", 22) );
names["Paris"].Add( new person ("albert", 20) );

From such an array/dictionary it will be easier to port the information into the format that you are looking for,

Add each object to an array list by using a loop. In each loop check whether the array list contain the object or not before adding . Then you will get a unique Array list of items

Or you can do this by using hash-map (key, value pair) . The key represent the place id and value would be the collection of places
