SQLite – How to Join Tables with Group

            MESSAGE TABLE                                       USERS
msg_id | msg_to | msg_from | msg_body | msg_date            user_id  | user_name
  1       1          2         hi      22/1/14                 2          jeff
  2       2          1        hello    22/1/14                 3          john                 
  3       1          2        howdy    22/1/14                 4          james
  4       2          1       nothing   22/1/14
  5       3          1        yes      22/1/14
  6       1          3         maybe   22/1/14
  7       4          1         no      22/1/14
  8       1          4         cool    22/1/14
  9       4          1         hot      22/1/14

*note that user 1 does not have any data in the users table.

I am having an issue getting all the messages uniquely in a stream based on who it was sent from. That is I want the last message that is exchanged between each user who communicates with user 1. I am trying to populate a list that should should the last message exchanged, so the list would be similar to this

          MESSAGE LISTING
     name      |         last_message
     jeff                   nothing 
      john                  maybe
     james                   hot

Last messages exchanged between user 1 and the other users at all times, user 1 does not have data saved in the users table but I have access to his user_id if needed in query.
I tried doing a JOIN with the users table ON msg_from = user_id but this only returns the last message from one user, so the last message exchanged between user 1 and user 2 is howdy instead of nothing based on this sample. I am not quite sure how to tune this query to represent the correct dataset that is needed, any help would be appreciated thanks.
