What are the dates associated with these addresses?
In 1896 the highest even number in Balm Green was 32.
I have downloaded the relevant part of an 1896 insurance map at https://www.oldmapsonline.org and will email it to you. Using this I believe you can pinpoint 35 Orchard Lane on image s18474 at PictureSheffield.
Thank you very much for the information, that's great, the dates for Orchard Lane are from about 1851 to 1891, I can't find the Balm Green ones at the moment as I have stopped my subscription with Ancestry for a while and it won't let me look at my info
I have just had a bonus, I was looking at my tree and a photo came up of my great grandfather from someones tree in America, I will now have to subscribe again as it won't let me contact that person until I do
