Briens death Edenderry

[whales]

Hello,
Are there civil BMD records in Ireland as in England.   I know there wasn't any before 1922 due to the uprisings.   I'm looking for my Gt. Grandfather Henry Briens.   The name became O'Brien.   I have written to the register office and there is no Henry O'brien registered.   I now know that when he married his name was Henry Briens.   He lived in Edenderry and I was told that he died in 1935, he would have been in his eighties.   I would be grateful it anybody could look it up for me.   I've been looking for it for years.

Thank you.

Marie.
