Hi Chesilcove,
Just to mention that I've just found out from the d/cert of my gg grandfather - James Ewen Mackenzie - that he died at 28 Marloes Road on 9 June 1876, although he lived at 128 Wornington Road. I've just 'googled' Marloes Road and it was Kensington Infirmary and Workhouse (known after 1922 as St Mary Abbott's Hospital) - as Casalguidi's previous post.
