Can I obtain an Irish Passport?

Question

I am married to an Irish citizen, who became an American citizen several years ago so he holds duel citizenship. We have a married daughter who lives in Ireland with our four grandchildren and her husband is also Irish. We travel to Ireland three times a year. My husbands entire family is still there. I live in US, had two Irish grandmothers, Eleanor Murphy and Susan O'Neill who were both left as orphans when they arrived in the states. There is no records that I can find on either one of these women including birth dates, etc. I would like duel citizenship but need to know if I qualify.

Answer 1

You can only claim citizenship through marriage if you are resident in Ireland for a continuous period of one year immediately before the date of your application. You also must have been living in Ireland for at least 2 of the 4 years before that and intend to continue to live on the island of Ireland.

Irish citizenship passes through three generations so you may be entitled to apply have your birth registered in the Foreign Births Register because your grandparents were Irish, but I can see your problem in not being able to get records to prove this. You are required to have the following documents for a grandparent:
Long form civil Irish birth certificate, if born after 1864
Baptism certificate, if born before 1864, or a search certificate showing that no civil Irish birth registration exists
Civil marriage certificate, if applicable
Death certificate if deceased
