Just found out that my Collins family lived on Mardyke Street, Skibereen.
Michael John Collins (b.1876 who married Jane Byrne in St Pancras, London in 1905 & is my g.grandfather), Henry & Cissie, all children of Denis Collins,wife unknown.
The 1901 Census shows Michael Collins b.1853 & Margaret (Casey) Collins with children James b.1881 & Norah b.1884 as living there & the 1914 Postal Directory showed Thomas Collins living there.
I believe there is a family connection as Denis my g.g. grandfather would probably be brother of Michael on the Census as the ages are correct.
Henry, Cissie & Michael Collins b.1876 from my tree definitely lived on Mardyke Street with their father Denis who was a baker. Henry took his nephew, another Michael, to show him the house they lived in about 1956, I believe it was derelict at this time.
Any help on this family would be really appreciated as I keep hitting dead ends with all the Michael Johns's, John Michael's & Denis's.

From my last post now have more details & am looking for more connections.
