hi anthony
i guess it is poss that he might be, but i don't know when he died yet.
as for the james gormley, the address is right it was no. 20 they lived in but there is no james on the census for 1901, he could have married by then and moved so there is a good chance that he is another brother.
as for carrickhill place my mother lived there with her grandparents and their family, the jane o'boyle you listed was my mothers aunt, it is poss that your mother might have known the family, my mother would have been 11yr old when your mother was born, but by 1933 she was living in sydney st west by my fathers family.
the rest of the o'boyle clan that lived at 9 crrickhill place were
mary ann (my gran)
john died in 1965
lucinda married frances coogan
clara ( i think died as a child)
agnes teresa married melville matthews
catherin married daniel mcneill ( i think he lived at no.9 until about 1952)
jane ( you listed never married )
edward married mary agnes conns
