ghawranmo' Qang, omelette De'mey DIghojpu'.

We learned the omelette recipe, because of gowron, the chancellor.

Now read this:

ghawran Qangmo', omelette De'mey DIghojpu'.

We learned the omelette recipe, because of the gowron chancellor.

Which is the correct one ?

I'm leaning toward the latter, but I'd like to make certain, that the title/rank *does* indeed behave as a "normal" second noun, in a noun-noun construction.

ghawran Qang is a noun phrase, though it is not a noun-noun construction. The syntactic suffix encompasses the entire noun phrase to which it is attached. Therefore the correct form is ghawran Qangmo'.
