It helped me to start with a 'Mind Map'. Not sure if you know what that is. I included everything and everyone, even outer people in that one. Then, I circled all the ones I thought possibly could be alters. It was getting pretty confusing by then so I transered onto another sheet all the ones I thought could be alters and put them in some kind of order by using coloured felt pens. Then, because I'm a drawer I sequestered myself away from everyone for a few days and started to draw or move my pencil around the page to see if I could either represent or give some kind of indication what they looked like or what symbol/icon represent them.

It actually was very helpful at first to show me myself.
