No occupation for John.........their is one for George but I can't read it! it would appear to begin with C and contain 6 letters, if I had to guess it would be a Carman (a form of salesman) but I wouldnt be confident that it is Carman.....................
The 1841 is very basic in what it provides.............it doesn't give relationships or birth place............other than in County = Y or yes.........
or Out of County = N or No............ie in or out of Middlesex = Y or N
Their are no Street numbers recorded on the census, which is not unusual for the 1841................
The 1841 has a rule on ages.........it generally rounds them down to the nearest 5 or 0............ie 20-25=20, 25-30=25 etc ........with the two ages being neat on 20 and 25 for George & John probably means that rule has been applied here?
Wentworth Street is full of Lodging Houses and in one of them is
WENTWORTH STREET SOUTH SIDE, ST MARY WHITECHAPEL, TOWER HAMLETS, MIDDLESEX
ANN SHEEN 20 NIGHTLY LODGER IRELAND
----------------------
the house that George & John are in.........is only occupied by them and Mary Smith
WENTWORTH STREET SOUTH SIDE, ST MARY WHITECHAPEL, TOWER HAMLETS, MIDDLESEX
GEORGE SHEEN 25 C?

? Y (BORN IN MIDDLESEX)
