I am going to try to answer this to the best of my abilities.
I do not know the specifics of where they were held, but I do know what they are & their significance.
All the Buddhist councils are meant to preserve the Dhamma the Buddha formulated & to discuss the Tipitaka & its interpretations. 
Buddhist councils have not consisted of all schools unified, although in some cases they have been. 
I hope my answer suits you well! :) 
May you be well.
