There is no teutonic family tree in the campaign. The reason is the dual family tree set up, example ireland:
Code:
relative Brian O'Neill, Jill, Domnall O'Neill, end
relative Connor O'Brien, Ceara, end
O'Neill is the 'official' tree whereas O'Brien is a 'secondary' tree. No idea if it is intentional, but it works as intended - it's simply not used normally.
The earlier mentioned scotland however is straight forward, not even a surname:
Code:
relative Alexander, Margaret, end
Here the aforementioned heir issue comes into play as Patrick Dunbar, being the second character in descr_strat, becomes automatically the heir as no heir is defined otherwise. No such problem with ireland as Domnall O'Neill is the second character but still not defined as heir, just a related trait which does not automatically makes him heir.
