I am afraid you have misled us with the Census info, RG9/352 is in the 1861 census not the 1871, that is RG10.
I have looked at the page in question, scrolling back thro the pages to where a street name is shown, folio 141. I read it first as Laburnam St but when I looked at the Street index there is no Laburnam Street shown, so I scrolled thro. looking for any likely similar name within the 140 onwards folio nos. I found a Salamanca St folio 141. On lookinng again at the original image I can see it is Salamanca but the writing leaves a lot to be desired.
I did check the enumerator's schedule for this piece no, District 15 in the St Mary, Lanbeth Church First area. Wouldn't you know it.... it is missing.
If you are in any doubt about this, an inquiry at the Census dept of the National Archives may help to clear it up as they hold the original schedules, it was useful at the old FRC when they had the census films there, I had occasion to request some help on a difficult census entry & they 'phoned Kew & got an answer straight away, sadly those days a long one.
I hope this is a help.
