Dietrich I of Isenberg

Dietrich I was disinherited of all his territories in the Holy Roman Empire (present-day Germany) following the execution of his father, but with the military support of his uncle the Duke of Limburg (Vesdre), recovered a small territory out of his previous possessions.

Everhard for more than 30 years, together with his father, contributed the struggle for the conquest of the county and former allodial Isenberger family property.

Other grandsons, Diederik II lord of Stirum and brother Frederik canon in Cologne, were not short of anything.

Were, not hear of the line but as descendants, richly endowed with allodial estates, Stirum castle and associated lordship.

There was no straight fief and primogeniture, but a well-considered balance between the then legitimate inheritance rights of his sons and daughters.
