Please enlighten us poor novices Thanks. I have relatives in Fulham Chelsea etc'
If you are not using findmypast but ancestry instead, or the street searches are throwing up rubbish results as sometimes happens the following may be useful - I haven't done it for a while, but down the page here are blue links to the different years
http://webarchive.nationalarchives.gov.uk/20100202110737/http://yourarchives.nationalarchives.gov.uk/index.php?title=Your_Archives:Historical_Streets_ProjectHEre is the 1871 Chelsea street index page

Lawrence Street Cheyne Walk 30-31 RG 10/74 57-58
The you can go on ancestry, search, instead of entering names and places choose 1871 census collection on the right, then scroll to the bottom and choose England 1871 census, leave the name blank, lived in chelsea, london, england, then you'll see 'Piece', that's for the two numbers after RG. in this case 10/74. The last numbers, in this case 57-58, goes in Folio.
Sometimes ancestry still wants to muddy the waters with results it thinks you want to see, but in this case the second one down was no. 31 Lawrence street so not too bad.
It sounds complicated dissected like that but once you've done it a couple of times it really isn't at all
