I'm not sure about it but perhaps I may be of assistance. My wife is a born DENIG and her family already did some investigations into their GERMAN line(s). I've set myself to gather all loose ends into a proper genealogy program. I'm for some time member of the German and the Dutch genealogy associations. But I use dutch software and I'm able to create GedCom-files. Although I donot know what you're investigating, this contact will perhaps lead to mutual assistance of any kind!
