Hello Cullenfamily,
I think the general trend of the comments are suggesting you may be missing a generation and the parentage is more likely the Creighton and Gara combination.
Details from the Parish registers and burials for residents from Aughalour for Andrew and his wife are below
Mrs Andrew Creighton(Mannion) Feb 9th 1891 aged 73
Andrew Creighton Sept 8th 1891 aged 85.
The corresponding Civil records are likely to be 1892 for Andrew and 1891 for his wife. Given the ages and your marriage date it is more likely her father was Michael which you could solve by obtaining the specific details from the Civil record entry.
