Okay, I'm confused! I obviously didn't post the last query to myself, so who did?
Whoever you are, yes, I know my great-grandmother's name, it was Julia (born 1872).
Her parents were James Mannix, born Gorticurrane, date unknown, and Johanna Murphy, born Glen, Minard, date unknown.
Her siblings were
Patrick b unknown
James b 1867 bap 2 Jan 1868 died young
John b 1869 bap 16 Feb 1869
Catherine b 1870
Denis b 1874
Maurice b 1872
James b 1874 bap 15 Mar 1874
Hannah b/d unknown
James' parents were James Mannix, details unknown, and Mary Kennedy, details unknown.
I've also recently discovered through family that Julia Mannix Ashe died after 1908 (youngest child born), but probably before 1920, as she died while family was young, and her eldest was born 1899. I'm hypothesising that it was before 1915.
