Hi Jayne
I have been looking for you when i noticed the info about the database
UK, Incoming Passenger Lists, 1878-1960
This database is an index to the Board of Trade’s passenger lists of ships arriving in the United Kingdom from foreign ports outside of Europe and the Mediterranean from 1878-1888 and 1890-1960....
So in regard to this I think Emma and her children fall outside these dates and am assuming they arrived in the UK in very early 1889. As Edward died in November 1888 they would have obviously left soon after and arrived in 1891 as the journey to and from UK in those days took about 2-3 months.
So unfortunately no records here on line.
