Hello Victoria,
How exciting that you are researching your Irish family roots! I hope I can help you with some useful information.
From 1864 onwards births, marriages, adoptions and deaths were recorded at the
General Register Office of Ireland. Here you can browse these records
online.
On our Community forum you can also find some
useful links - depending on how many avenues you already have tried, we hope you might find something here that will help you find the certificate.
One more very helpful organization is
Ireland Reaching Out - a volunteer initiative that aims to connect the Irish diaspora with their Irish family roots.
I hope this is helpful! If you have any more questions please feel free to reach out. If you make any discoveries also please share with us here if you like - we love hearing success stories! I wish you the best of luck with your journey to uncover your Irish family history.
Warm regards,
Vera
