Try this list of Eastmarch quests to see if you can find the last one you did.

I did at first, too - but what I can suggest is going to each area on the map that looks unexplored, so.. say that you see a bit of a path, or just simply an open area full of grass, go there and look around for a quest pop-up.

Eastmarch has you go in a big counter clockwise circle around the zone. You need The Better of Two Evils or the next quest Eternal Slumber. Your on the right track if you have to look for villain who wants you to then find something for him with the Lifeline quest. (trying no to spoil this too much)
