Along the way though I did find this Gazetteer for Averland by the same guy who drew the maps. He says he gets his data from Sigmar's Heirs but to what extent I dont know. Once I get the book I'll find some hard evidence.
Averland Gazetteer:
http://www.madalfred.darcore.net/gazetteers/Averland_v2.docAccording to the above, the following Leitdorfs are named: (This again I believe is an original work by Mad Alfred, but maybe some of it is taken from text fact)
The Leitdorfs Control:GRENZSTADT - Count Jens Leitdorf
HEIDECK - Countess Magda Leitdorf
STREISSEN- Bailiff Franz Döbreiner for Leitdorf family
WUPPERTAL- Count Kastor Leitdorf
Also, here is a nifty article about Imperial Nobility (Coat of arms etc) It details who leads and who succeeds. Good read all around, may prove useful.
http://www.madalfred.darcore.net/articles/NOBILITY.rtfDoes anyone own this text(Sigmar's Heirs)? Mine is coming on ebay still and I was wondering:
A) How accurate is this data to this book?
B) Does anyone know who Marius was married to? Marlene Apltraum?
C) Would any of the above counts take precedence over Hans Leitdorf?
D) Does it support the above posted Gazeteers
