This is all great stuff, I will need to tie some stuff together on my end but you have all the connections there.
Leslie Scott and Elizabeth Keatley had several children I was aware of:
Daisy Connor
John Connor
Edith Connor
Annie Connor
Violet Connor
We thought Violet had been married to someone named Leslie Scott but that may be wrong. We also got the name Violet Noonan from an old notebook my grandmother kept.
Pretty certain the Annie Josephine you found yesterday is Leslie and Elizabeths Annie, the pieces fit.
There was a Mary Keenan that my grandmothers children called Auntie may. There were stories that she was a child Christopher keenan had out of wedlock.
She later married and had a Daughter named Maureen who is dead now. I believe the surname when she got married was Kane/Cain or some variation of that. Not sure this is the same Mary Keenan though as the dates dont match up. This Mary died later than the one reported by Annie connor.
I would hazard a guess that the Mary Keenan whom Annie Connor was the informant of, was some relation of Christopher (Sister/Aunt/Cousin) and Annie was living with her. I get the impression that she must have fallen out with her mother as she uses the name Connor while working as a maid.
We were aware that she had married John Killick but had never really gone down that road.
Just on John Leslie's brother Willis. We originally thought that Elizabeths first husband was a doctor and went looking for records in the Royal College of Surgeons. Naturally we found nothing but now that we know it was Willis that was the doctor, it may be worth re-visiting for confirmation.
on a side note, John Killick owned a photography store in Bray Co.Wicklow, on the same street as his address in the previous census record.
