There's a mysterious great-uncle, whose initial I only know, living at a house in Dun Laoghaire in 1938. Are there electoral rolls or rates records or similar for that period (not online obviously) that I could consult, does anyone know?
There are Thom's Directories at Ancestry up to 1946 if that's any good.
Or if you can visit the Dublin City Archives at Pearse Street Library you can view electoral rolls from about 1937 to 1963.
DCLA electoral registers are only for Dublin city, not Dun Laoghaire.
Try the local studies dept of DLR lexicon library for DL electoral registers.
Ah flip - I did think that might be a possibility.
There's also a possibility Fingal has them. I've looked at electoral registers for places like Tallaght and Newcastle in Fingal Archives.
If it is an unusual surname, you might be able to get some reference to him in newspaper reports of social or sporting activities.
A very common name unfortunately!
