Going back over the family tree, I noticed that my great-great-great grandfather died in the Dublin Union Workhouse in 1930 and my great-great-great grand mother died in St Kevin's Hospital in 1937. It seems that The Workhouse became the Hospital during the time of the Free State, but continued on as a workhouse type set up.
There is nothing to say when they were both admitted, but both have different addresses listed as their residence when admitted on their death records so it looks like they were admitted one after the other. Unfortunately the dates of admissions online don't go up as far as 1930 so I can't check. The mother's address when admitted looks like she was living with one of her daughters.
I'm just wondering whether it was normal for the elderly to end their days in a workhouse in the 1930s? He was a painter and she was a fish dealer so as they got older he couldn't keep up working I imagine? So with no income was the workhouse the only place left? Would it be normal that they both be admitted separately? Or could it be that they just went there when terminally ill, using it as a hospital more than the only place of refuge left?
