This is a road running EW just south of Melior Street, where Our Lady of Salette is to be found.
15 Snowsfield was the 1888 'home' of the 'destitute' Stephen Lyons when he was admitted to the workhouse- meanwhile his wife Catherine was listed as living at Millstream, to the north and just east of the future Tower Bridge Road.
Also ,in 1861C, David & Margaret Tobin, with children Eliza & John, are living at 9 Victoria Cottages, which the Our Salette priest told me, in 2009, were off Snowsfield.
And, White Lion Court, the 1911-1917 home of Stephen Lyons 1859, was off the east end of Snowsfield.
