Dear 0113vanny, hello again,
in the 1881 census I found two Wittman families being pork butchers and originating from Germany.
1. Frederick Wittman, *1842, married to Christina, *1847, 315 High Street, Attercliffe, Sheffield
2. George Wittman, * 1845, married to Mathilde, * 1852, 7 Waterworks Street, Sculcoates, Hull. In the family there lived also Dorothea Wittmann, *1813, mother of head. And there was a servant registered at the same address: Christina Schum, *1861 in Württemberg. Interestingly enough, in 1891, there was the shop of George Hohenrein, another German pork butcher at that address. He apprenticed a Christian Wilhelm Küstner, *1873 in Rüblingen and there were three other assistant butchers who also came from Württemberg: Henry Kulsch, Marie Schumann and Rosina Kurz who were also living at the same address. By 1904 Küstner had his own pork butcher’s shop at 165 Princess Road, Manchester.
In Otley there was only one German pork butcher at the time: The Weegmans who still exist. Perhaps you can phone them and ask whether they know where their forefather originated from.
In my personally created butcher archive I found a Frederick Steinbach, *1858 in Langenbeutingen, pork butcher in Liverpool and married there in 1885 to Louisa Edwards.
Perhaps this information may be of some help to you.
Best wishes
