Is it possible that 25 Leinster Square, Rathmines might of been an unwed mother's home? or one of those horrid places run by nuns where wayward children were placed.
There is no Nora Combie in the 1911 census in Ireland. Perhaps a fake surname?
There are Combie's in the 1911 census in Dublin, Nora Combie would need to have been born by 1911 to be of legal age to register a child. It is possible that Nora Fleming became Nora Combie?
Tried to find the children on www.familysearch.org
William, Maureen and Kathleen but oddly it keeps reverting to the Prison records at Mountjoy or the US, give it a few days to straighten itself out and give it a try.
William Flaming, of 11 Newmarket, St. was in Prison in Mountjoy for having a ferocious dog at large?
spelling could be a poorly transcribed record.
Also tried William Fleming, born Wicklow 1870 - found nothing
