Made it!
Or rather... made one of my additional targets...

All people in my tribe, being dead or alive, are now JOAT! So I now have 100 living JOATs (plus 13 dead).

One thing you should understand is that they only need to reach master in all skills. After reaching master they can still improve a bit (unto fully maxed out). As I am still trying to get the last two trophies I decided (just for fun) to try and get all the living to the maxed out in all skills. None there yet, but some are getting pretty close...

Status on missing trophies:
Never a dull moment: 50%
Rub those sticks together: 48%

Also made my extra target of 1,000,000 units of food in the supply. Still working on the 1,000,000 tech points in store thing. Almost half way there...
