The census referred to was 1881:
Reference RG11, Piece 453, Folio 16, Page 27
3 Grove Street, St George in the East, Tower Hamlets
Wheeler, Paul Head M 54 Railway Porter b Germany (Mannheim has been added, but I wouldn't say it was scribbled?)
Wheeler, Emily Wife F 53 b Dartford, Kent
Wheeler, Charles Son M 25 Collar Cutter b St George in the East
Wheeler, George Son M 18 Shopman b St George/East
Wheeler, Rose Daughter F 15 b St George/East
The "Mannheim" would have been added probably by the enumerator.
The marriage entry (June qtr 1853, Bethnal Green, Vol 1c, page 528), shows both Paul Wheeler and Powell Wheeler, together with Emily Smith, on the same page.
