Ordnance Survey Map of South East Wexford
Ordnance Survey Map of West Wexford
Ordnance Survey Map of East Wexford
The above three Wexford maps are a great start to searching in Wexford
Old British Ordnance Survey Map
These are detailed maps of parts of towns or villages. Printed as they are there would be too little detail - best to extract a small area. Very useful if you want to see what a place used to be like rather than how it is now
This is the best map I have come across you can search down to street level.
This another good site well worth a look.
