Herbalist and Forester Lodge. I cannot overstate how crucial it is to have renewable supplies for long term survivability. You may also want to consider upgrading some of your houses to stone, that way they take less firewood to keep warm. Also, don't trust your food stores to stay full for very long, I had a town that had 2000 food going into the winter and by the next spring I couldn't keep 200 food in my storage barn even with two hunting lodges, two farms, an orchard, a fishery and a couple gatherers.
I really enjoyed the ending, the real gut punch the game gave me though was the quick glance over the table of all his dead friends before going down to meet his daughter. I still get a little misty eyed thinking about it.
