I'm in love, with one I ne'er could pair.
But call me not a silly goose, for they're in me.
I'm all for vendettas, but ne'er did kill a soul.
Yet for taking revenge you will need my help.
My next of kin is twice the man I am,
Yet named more for the one I followed in.
You have already missed me twice,
Now speak and tell me truly: who am I?
