The 1905 birth certificate for John Michael HICKEY gives his place of birth as 4 Columbia Square and his father Patrick is a garden labourer. The birth was registered by Kate HICKEY on 11 July 1905 so just short of 6 weeks after the birth.
In 1911 that house has a William HICKS (age 57, Gardener) as head with his family. I thought the name was oddly similar to HICKEY but I cannot find any connection.
In 1901 the house has Farrell CONNORS as head (35 Gardeners Labourer) with his wife (maiden name DAVITT from the birth of one of the children), children, a brother and two Boarders. All from Ireland apart from the two young children.
The newspapers do not show whether Patrick and Kate were lodgers to the CONNORS or whether they had taken over renting the house.
