Okay.
I looked it up and yes, your use is well done.
It is consonant with both how you said it and how I vaguely remember my grandfather using it.
For those not grasping our esoteric weirdness:
Fenian is essentially militant Irish nationalism.
This is distinct from being Irish or from (Irish) Republicanism.
Essentially how Zionism is distinct from Jewish nationalism which is also different from being Jewish.
I am not a Fenian.
The below image, which I saw while in Belfast, is a good example of why. It is an Orange (British loyalist) mural but I think it gets the sentiment of the city across. http://people.ku.edu/~kconrad/smural2.jpg
A good thing to remember is that the nobody kills more Green Irish than the Sinn Fein and IRA.
Not the Orange Irish and not even the British.
But Allan, yes, I would still love to have my own highschool insurgent cell.
