Hello again,
that would account for his not being there.
The child however is Jessie if I have the right one. I can't find a Silvia.
Mary A has 3 Gollop children, a Hodder son and Jessie. What do you think?
Ref: RG13; Piece: 2015; Folio: 35; Page: 20
I am searching 1850 +/- 5 yrs for John Roberts (which would bring up T) born Ireland and looking at those few that may be around the coast! (there are paupers/ vagrants and prisoners but no fishermen).
The nearest I can find which is a long shot is:
1871 RG10; Piece: 3742; Folio: 129
John Roberts aged 15 yrs born Wexford a pupil aboard a training ship - the Akbar which belongs to Liverpool Port.
Just looked that up and it was for the reform of Protestant boys.
It is difficult to trace Irish records as early as 1850s. I have looked on Family Search but there is nothing.
My last shot would be to check the witnesses to the wedding - and perhaps even the godparents to the Roberts child to see if any of them can turn anything up. He may have had children from an earlier marriage but Roberts is too common a name to try to sift out without other details.
