What would be a good place for a second village?
well let's see, from what I can tell, if you want to make a town to specialize in areas that your first village doesn't... like say, you want to make a village that harvests loads of iron or fish or salt and use it to supply your first village... then it should be close, like the same county or a county away.
if you want to make a less specialized village, and just go somewhere less active and try to get lots of honor and level faster, go for somewhere that is at least an honor circle away (probably 2 counties away at least) but not much farther if you want to boost its growth by sending resources from your main village.
the latter is what I did, I found a deserted area @ the south of fethard. other areas that look more deserted are ballingarry and mullinahone to the east, the parishes around dundrum to the north east, and the south end of lattin to the west. and since I went for a less specialized village, I didn't change the village type, but I still relocated the stockpile to between the stone and iron, because I produce a lot of wood in my main village and just send some over every time.
