It's the wrong family
STANLEY, JOSEPH
Mother's Maiden Surname: PASK
GRO Reference: 1843 J Quarter in SAINT PANCRAS Volume 01 Page 276
On the census Joseph, living in Marylebone, says he was born in the City (of London)
1881 says born City Fleet Street.
When he married in 1864 in Westminster, Joseph said that his father was Joseph Stanley, Carpenter.
This fits better in 1841, except it's John Stanley, Carpenter, not Joseph.
Possible in 1841 - though hard to be sure if it is hin or not without any more info
