Emil Haase and Luise Bühl, both born in Germany, married by banns on 30 April 1891 at St Georges Church, Battersea. Their address on the marriage certificate is 4 Currie Street, Wandsworth.
On the 1891 census, this is the address of one of the witnesses to their wedding, Peter Mechlet (Midster on A*****y), but they are not shown on the census at that address.
As the wedding was by Banns, I would have expected them to be nearby on census night, so where were they?
What makes it harder are the endless possibilities for mis-transcribing either of their surnames. (A****y has the wedding as Hoose and Bahl)

Any help would be greatly appreciated.
Bob.
