Powell Bros.

Owners of Llanhilleth Colliery between W. Crook's original sinking and 1879, when Henry Powell took charge alone. Not to be confused with Powell Duffryn or with Thomas Powell, both of which have their own rows here; add_operator() warned on the shared surname and the firms are distinct on the evidence read. No further company detail has been found.
