OK
That ref 1495 -310a for 1851, gives, 2 Derby St, St Pancras,
Thomas Reynolds, head aged 69, superannuation from excise, born St George, Hanover Square, Middlesex.
Will have a look in a minute and see if he is there ine 1841 and if there is any more info.
There are others at that address,
John H Wright head, widow, 71
Elizabeth Long, head, widow, 60
Amelia Hemmings, visitor, 34
Charlotte Enrick, visitor, 50
do you know any of those names?
