Hi Katie. I come to this from the angle of researching glassmakers (specifically paperweight makers) in the Birmingham / Stourbridge area in the mid 19th century, with the hope that someone has an item passed down within the family. However, I think that John and Thomas Harris were owners of the Belmont Glass Works, Banbury Street, Birmingham around 1820. By 1845 that was now owned by William Gammon & Son. Hope this helps, Alan.
