Presuming I'm on the right track, James' father is called Patrick.

RE: Josephine's birth certificate.
Her DoB relied on the 1911 census and the 1871 census. Now then, I've gone back to the 1871 census and it shows this:
James O'neill Head - Male 26 1845 - Ireland
Mary O'neill Wife - Female 23 1848 - Ireland
Bridget O'neill Daughter - Female 4 1867 - Ireland
Julia O'neill Daughter - Female 0 1871 - Lancashire, England
Edward McEvoy Boarder - Male 28 1843 - Ireland
This must have been where James came in. I'm pretty sure Currid, surname for Mary, must have come from either a FindMyPast suggestion, if not their marriage records. It may be nothing, but when I searched the Catholic baptism record for Julia, Mary was listed as Mary McEvoy:
Father: Jacobi Oneill
Mother: Maria Mcevoy
RE: Occupation
On the marriage record from 1891, he's named John and a police officer. In 1871, he's James and his occupation is a seaman. I feel like I've made an error somewhere, somehow. It's frustrating because one woman or the other has the same name(s), both are the same age and both are from the same place.
The witnesses on the marriage are Henrietta Petrali (John's sister) and a Thomas Evans.
