Where is this St Martin's of which you speak? somewhere in Warwickshire presumably.
Could it be Centre Row?
Is it Centre Row? There is no Century Row in the 1851Census Street Index. If it is Centre Row then, according to the 1851 census description, it was in the area of Hurst Street and Smallbrook Street http://maps.nls.uk/view/101584678#zoom=6&lat=1949&lon=2253&layers=BT although it is not marked on the map.Stan
