Tracing a branch of the Uzielli family tree

[AntonP]

I am trying to trace back the family tree of Douglas Clement Uzielli of the UK.
On 28.3.1888 he married Emily Alice Stewart in London. They had 2 children. I have the family details from this date onwards, including the death of Mrs Uzielli and the following trial (which seemed to garner 'News of the World' type attention) although I can find on pictures of either of them which is surprising seeing they were so sociable.
Specifically I am trying to work back from DC Uzielli to find his ancestors.
I was wondering if there might be anyone on Rootschat who has information on this family prior to 1888?
Thanks.
