its so True... i always believed if they were from northside or southside they stayed put, but from researching two sides of the family , at one point or another they went either side and then came back!!
Byrne is also one of the largest group of names, I haven't even been able to track down Patrick Byrnes death record, despite working with the genealogist at Glasnevin.
Had hoped Glynn would be easier. I think with the large portion of COI records being lost, this is a mystery that may remain unsolved!!
