1)History Foundation (fee paying so didn't look) Has Wicklow parish and civil registrations
the Government Registry Office
(will do small search)
(no luck for me)
Griffith Valuation would be the census substitute for
Dublin County 1855 and Dublin City-1846. so a lot of years before the 1901/11 Census.
Drumcondra is in Dublin North, and is both a Town and a townland and has two Parish's, Clonturk or St. George's.
I did find them finally at 48 Tolka Cottages, name listed as James surname, and I was looking for Devlin as the surname.www.familysearch.org
Nothing found for Dublin but this might not have Dublin City records.
Matthew James, birth registration Oct-Dec 1893 Rathdrum
I don't see any death records for someone of the right age, although there is Matthew born in 1872.
There a number of US Census with the name of Matthew James
There are a number of James from the s.w. area of Wicklow
the Shillelagh area. Not too far from Rathdrum (these are related to my husband's Codd family who left for Canada in 1819-1832.
Looked in WWI military deaths, none for born in Dublin,Ireland, but one is for Rathdrum but age didn't fit.
