Hello Christopher
Thanks a lot for your link to proni.
Any help would be appreciated...
I have a marriage cert for Sophia Rebecca 1866 Trinity Church St Mary Newington Surrey on it she states that her father was Thomas..a Hop Porter
On subsequent uk census we find her living in London and sh always states she was born in Londonderry.
I have what I think is her and her brother in London on the 1861 census Brother called John both born Ireland but no parents, living with relatives.
I assume her parents did come to England as I do not associate Ireland with hops?

any help please
