hi I am trying to trace info on my maternal ggg parents. I don't know her christian name or either date of birth. Owen and Miss Fitzgerald were Irish, possibly from Cork. They must have been born between 1820 and 1850 bcause their daughter, my gg mother Nora Finnigan, was born in Mallar Cork 1 Aug 1888.
Nora's marriage was 1st Aug. 1888, not her birth. She was "full age" on marriage certificate, therefore over 21. If that was correct, the latest year she could have been born was 1867.
Could "Mallar" be Mallow?
If she was born in Ireland after 1864 her birth should have been registered and her mother's Christian name and maiden forename should have been recorded. Birth, marriage and death registrations
https://www.irishgenealogy.ie/en Nora may have been short for Hanora or Honora. No Finnegan births registered in Mallow district before 1870s.
Nora's abode at the time of her marriage was Spike Island. Was her father connected to the army or navy?
P.S. Owen might also have been known as Eugene.
