This next piece of information is for you to look at too.
I assume this is connected to a pension application - again there are better informed rootschatters to interpret the record.
http://censussearchforms.nationalarchives.ie/search/cs/details.jsp?id=40996It seems to be an application from Margaret Kelly, the daughter of Daniel and Margaret. There is a reference to their marriage on the second image and to Mary, 6 months.
However, the groupings on the second image are confusing to me.
There is no reference to Daniel -apart from the note re the marriage so I wonder if the Kelly names are relevant to Margaret/Peggy Kelly and not Daniel.
The date of application - 1920?
The street address posted for the applicant - Mr J E O'Neill, Main Street, Maghera, Co Derry is, I wonder, someone of status applying on behalf of the applicant. As yet I have seen no connection.
I hope all this makes some sort of sense!
