This jeweller, watchmaker, and optician can be traced to Silas Henn (1822-1902), who was from Tipton, Staffordshire.  A Methodist preacher and writer of religious texts, Silas handed over his watch and jewellery business to his son, John Wesley Henn (1848-1914). The shop was at Dudley. 

J. W. Henn had two sons: Thomas Austin Henn (1870-1948) and John Wesley Henn Jun. (1872-1959).  Thomas Austin started his own jeweller’s shop at Wolverhampton (as T. A. Henn & Sons Ltd it is still active).  John Wesley Henn Jun. had a shop at West Bromwich after 1887. He was later joined by his sons, John Wesley Henn and Winston T. Henn. The firm was registered as J. W. Henn & Sons Ltd in 1941 (after another business at Dudley had been acquired), with £10,000 capital.  J. W. Henn Jun. retired in 1946 and two years later the firm went into voluntary liquidation. It was then reincorporated. This was so that his sons could own its constituent parts:  the elder son, J. W. Henn became managing director of the West Bromwich business; his brother, W. T. Henn, had charge at Dudley. John Wesley Henn Jun. died on 14 February 1959 in retirement at Torquay, leaving £32,108 gross (£31,704 net).  He had been a lifelong Methodist (Birmingham Post & Gazette, 17 February 1959).  J. W. Henn & Sons Ltd continued to trade until 2002.
