Hi 
Phil - George gives Forest Row as his birth on the 1881 census:
1881 England Census
Cherry Orchd Road 1 Park Cottages, Croydon, Surrey
Geo. LANGRIDGE   Head   M   Male   63   Forest Row, Sussex, England   Carpenter  (1818 )  
Eliza LANGRIDGE   Wife   M   Female   55   Croydon, Surrey, England        
Harry LANGRIDGE   Son      Male   22   Croydon, Surrey, England   Painter     
Wm. LANGRIDGE   Son      Male   20   Croydon, Surrey, England   Labr     
Alfd. LANGRIDGE   Son      Male   16   Croydon, Surrey, England   Stable Lad     
Lillie LANGRIDGE   Daur      Female   14   Croydon, Surrey, England   Scholar   
Looking at the map I realise Forest Row is close to EG a lot of my Langridges give Forest Row EG as there POB
Andrea - I also use a naming theory to try to establish children and parents. On BMD there is a James born Mar 1848 Croydon which fits James son of George on the 1851 census
  1851 England Census
Middle Heath Lane, Croydon, Surrey
Croydon, Surrey
Eliza Langridge 23  ( 1828 )
George Langridge 28  Builders Labourer ( 1823 )
George Langridge 8 Months  
James Langridge 3  
I viewed the image as there was a star beside it and although the image is very unclear this James had a middle name of I believe Samuel - could be wishful thinking on my part
