Hi,
I have checked with local historian today in regards to 137 Dysart Rd and in the late 1950s the workhouse had been changed into an auxiliary hospital and at the back section was turned into a maternity unit.Incidentally my husbands Grandmother died in the hospital section in 1960 and the historians daughter was born there in 1958 and my son was born there 1966 so it looks as if Jonmars uncle died in hospital and not the workhouse.
Hope this info is useful.
