Hi cannot locate Daniel at present in 1861, but their are known problems with missing pages in certain areas of London, he could be on one of them, but in 1891 he is with his brother William both shown as Peddar on FindMyPast aged 19 and 16 working for George Thrower a Butcher on Census Ref RG10/222/94/91

Eliza 26 b Kingston, Surrey
Eliza Ann 3 b St Pancras
William 2 b St Pancras
Residing at 3, Union Street, St Pancras
