Right. I'll be daring and attempt to explain my answer.
Nimble Fingers=Miriel (her epesse Serindė means 'needlewoman')
Fell fire=Feanor ('spirit of fire', etc etc)
Wounded fox=Maedhros (gained the 'fox' nickname due to red hair)
Bright jewel=Silmaril
So ... I s'pose it's Finwe's line, as Miriel can't be said to be of the House of Feanor.
