I'll look into it some more for you but recent family is as follows
Sandymount, Dublin 4
John Iremonger two sons James (Born 1922), John (born prior to 1922) and a daughter (decease when a child).
James Married to Briget Smith - 2 daughters (Josephine (has 3 daughters), Geraldine(has two daughters and a son)), 3 sons (Andrew, Bernard(has a son and daughter), Stephen)
John also married - 1 daughter (Anne (4 or 5 children))
Father's name unknown but cousins to the John and James above Arthur, Colette, Valentine (he was a poet so he may be more traceable)
Arthur had at least two sons (one decease)
Valentine 2 daughters (one deceased) and a son
Not much I know but maybe of some help.
