I suspect that this is a question that comes up all the time, but here goes.
I have used, to good effect, irishgenealogy.ie and geni.nidirect.gov.uk/ to search for birth death and marriage information (register entries, certificates etc.) for my Northern Irish ancestors.
The former says:
"The years covered by the release of the historic records of Births, Marriages and Deaths are:
Births: 1864 to 1923, Marriages: 1845 to 1948, Deaths: 1871 to 1973"
The latter says "You will be able to search for death records which are over 50 years old."
So how to find details outside of those ranges? For example, how does someone find death details (registry entry or certificate) of someone who died, say, around the year 2000?
How does genealogy (at least in NI) function with these limits? How does anyone find details of someone born earlier than 1864 or who died later than 1973?
Am I missing something? Thanks.
