Long time since I posted, but the records here are extremely confusing.
The marriage of James O'Connor to Sarah Clark, in 1881, lists both as having been previously married. James is a "Widow" and Sarah a "Widower" to a man of surname MacVicar. James' parents are straightforwardly listed as:
William O'Connor = Ann McGee
James on the marriage is 50, Sarah is 40. They appear together on the 1881 census, at the same address of 7 Armour Street mentioned on their marriage. By 1891, they appear to be at 68 Barrack Street. James then dies in 1897, and this is where it gets bizarre. His previous wife (mentioned on his marriage to Sarah Clark implicitly) isn't here. His wife is indeed Sarah Clark on this record, but his parents are:
John O'Connor = Martha King
Sarah Clark then dies in 1909, listed as a widow of James O'Connor. On both her death and his death records, he is listed as "Army Pensioner".
I return us to the 1890 death of Jane O'Connor (wife of James O'Connor) in 7 Armour Street. What is going on here? We have two James O'Connor individuals maybe? If Jane is his wife in 1890, and he married in 1881 to Sarah - well, this would be bigamy. Was Jane in reality the earlier marriage referred to in the 1881 marriage, except that he had never truly been widowed? Or was this just another James O'Connor, related to the James who married Sarah? What is his genuine parentage?
All very confusing, and still not even sure if Teresa was son of this particular James and Jane! Her marriage to Eugene Gallagher in 1893 lists James O'Connor as dead, which would contradict the 1897 death of this James who was married to Sarah.
