Where are you, Daughters of United Sons of N.C.?

This eBay item caught my eye. Handsome badge, grand name — but Google returns no  mention of the Daughters of the United Sons of North Carolina (and only a 1932 tax reference to the United Sons themselves). I’m skeptical of the seller’s “Civil War Confederacy” designation.

Complicating the question is a ribbon in the collection from the Supreme Grand Lodge of the Sons & Daughters of North Carolina, a black fraternal society “organized mainly [according to a 1900 letter in the New York Times] for benevolent purposes — to foster a feeling of friendship and brotherly love among the North Carolinians in the North.”

Might these similarly-named organizations been related — or even the same? Is there an expert in  Miscellany land?
