[Pitchwife]

Húrin and Hardang (or whatever his final name was - the Halad of Brethil, aka Mr "Give-the-old-carl-a-stool") ?
Don't have War of the Jewels at hand to check all the details, but off the top of my head -

Blind man and deaf man
Húrin - blind to the shadow he brought with him, the Halad - deaf to Manthor's wiser counsel;

First of them second.
Second's - third house.
Húrin from the Second House of the Edain, the Halad of the Third;

forest and garth
the Forest of Brethil and the enclosure of Obel Halad;

Rich man and poor man
When they first met, the Halad was a wealthy ruler, Húrin a poor wanderer; but at the moot, Húrin gained the support of the people (= became the rich man, metaphorically), while the Halad lost it (and subsequently his life);

Enemy and a son
not far away.
This is what first made me think of Húrin: both his son, Túrin, and the son's enemy, Glaurung, died 'not far away' from the scene of this tale.
