Juggling life, liberty and happiness

On some of the illustrationsin the Hofkleiderbuch (Abbildung und Beschreibung der Hof-Livreen) des Herzogs Wilhelm IV. und Albrecht V. 1508-1551 - BSB Cgm 1951, you can see the initials MHG or EMHG on the sleeve.

After doing some sleuthing, I've determined that it was not the Duke's family motto. Their family motto was "In Trau Vast" according to this page

So this is my best guess of what the letters mean:
E - Eifer which according to my dictionary means "Eagerness, zeal, ardour, fervour, passion
M - Meines
H - Herzog
G - Gott

So perhaps a motto for the servants of the Duke? "Eifer für Meines Herzog und Gott"
Translation: Zeal for My Duke and God
