Thank you all so much for helping me. I will now contact Sheffield Archives to see if they have information on graves in the cemetery and hopefully get an ID number. I now live in the West Midlands so although I am disappointed at least I wont be making an unnecessary journey to visit the cemetery.
Josephine,
Looking back on earlier threads about "Loxley cemetery" there has been confusion between the Long Lane section of Loxley Chapel and Wisewood Cemetery.
Suggest when you contact the Archives that you check both these possibilities.
