Morning Gadget!
I have both the death and birth cert. of the Sarah Ellen Cahill you entered. I was hoping the age had been put down incorrectly. However she was the daughter of a Michael Cahill of 4 Siddons St Litherland. She died at 5 hours of age from a "Premature Birth. Insufficient vitality".
Just in case you keep looking, I also have a Marriage for a Sarah Ellen Cahill to John Connor in Kirkdale Liverpool in 1910. I thought she may have re-married. Sorry, but it is not her.
I will follow up your suggestion using just initials and * .
I am not aware of any relatives in Ireland. But would not discount the possibility.
James Cahill did have a brother, Richard, born in Liverpool.
I am pretty sure he appears on the 1891 Census living at 49 Orry St Liverpool with his wife Mary Kate who was born in Co Wexford.
In the 1901 Census Richard & Mary are living at 21 Ascot St Liverpool. Ascot St had been an address used on James and Sarah's Marriage Cert. in 1887.
Many thanks for your interest.
Alan
