See "The Diary of Jorge von Ehingen" by Malcolm Letts, F.S.A., London Oxford University Press. Humphrey Milford 1929.....great stuff. Soldier of Fortune
Also, Kilchberg Castle in Tubigen was occupied by lineal decendents from 1402? to about 1958 when the last decendent died. Big stuff around there. One of the family castles is now an inn. Sold in 1742? We stayed there about 30 years ago. Family name in high regard. If important, I will try look around for info.
