i am orginally from bayside and my parents address is XX Alden Road/Park/Drive, Sutton, Dublin 13. Always thought it was very funny. My neighbours use XX Alden Road/Park/Drive, KIlbarrack, Dublin 13!
I have never seen anybody use bayside in their address. I think bayside is in an area known as "mid-sutton"
I think you are in baldoyle!
ps. bayside ends in sutton park, i believe, but the real bayside houses are around the square etc. i.e. bayside boulvard etc. Houses around "Bayside School" are not really bayside (like my parents) but use sutton in their address.
