Hello,
That census will take some explaining. 
Thomas ANGEL, senior b. 1820 Paisley, Renfrew - not yet found anywhere in 1851.
Thomas ended up in England where he married a Mary CLEMENT.
From Cheshire BMD site Thomas ANGEL married Mary CLEMENTS in 1843 (Stockport), it also states a civil marriage. In FreeBMD Choose Cheshire:
Marriages Sep 1843
ANGEL Thomas Ashton &c 20 79
CLEMENTS Mary Ashton &c 20 79
Children born in England:
Thomas ANGEL, junior
Births Sep 1844
Angel Thomas Ashton 20 20
John Clement ANGEL
Births Dec 1846
Angel John Ashton & 20 17
Hannah ANGEL b. ??
Death: Abbey (Paisley) 05/12/1851 Hannah ANGEL
So two questions:
Where and when was Hannah born?
The fact that Hannah is not there would suggest she was born after the 1851 census.
Where was Thomas senior in 1851?
His spouse and their two children where living with his brother Samuel and his family in Paisley.
Regards,
Dave
