Lancaster's Steam Coal Company
Took over Rose Heyworth Colliery at Abertillery in 1888 and worked it until the industry was nationalised in 1947. Almost certainly the same Lancaster interest as the John Lancaster and Company that sank Six Bells a few miles away from 1892, though no source read here states the connection.
