I would be interested in any information about my Henderson ancestors who hailed from the Northeast - Durham and Newcastle, who moved to work as glassmakers in Walton on the Hill in Liverpool (Crown glass making?), then moved to St Helens and briefly to West Bromwich where the family are found in the 1851 census living on Spon Lane. There was an innovative factory here pioneering the manufacture of sheet glass and at this time they were making the huge panes of glass for the Crystal Palace for the Great Exhibition. Any information about Robert Henderson (b1814)as a glass maker, John Henderson (b1840)who was later a glass painter in Manchester, Edward Henderson (b1850) glassmaker or David Griffin Henderson or information relating to the movement of workers to West Bromwich from St Helens to work on the Crystal Palace would be most wecome.
