Hi Sally, our volunteer has asked that I reply with the following information
That school in Blessington was named after a 'Joshua Iremonger' (born Wherwell, Hants) - he died childless in 1778 and his widow Penelope left an endowment to the school, the School was later taken over by the Educational Endowment Commissioners. (src : The Manor of Blessington, Thos. U. Sadleir, The Journal of the Royal Society of Antiquaries of Ireland, Sixth Series, Vol. 18, No. 2 Dec. 31, 1928, pp. 128-131 5 pages)
Penelope (nee Morgan) was previously married to Charles Dunbar - some further details here, and here.
There's a previous query on IRLXO message board which mentions this school - if I remember correctly the family in question was Sargent (probably a spelling variation of..)
I saw a query on a Dublin business (Green) so checked a few of my directories... the only definite match by surname and address was from 1847 and 1848, no firstnames unfortunately, but there were some other Greens in the same type of business which I also included...
There are two George's St. in Dublin city, Great George's St South and Great George's St South, the first
is off Great Britain St. (now Parnell St.) north Dublin city and the second off Dame street Dublin south city.
North Gt. George's St. numbers run from 1 to 55, South Gt. George's St. has numbers 1 to 90.
In alphabetical Listings, e.g. directories, these are often listed as : Greorge's St. Sth. Gt. or similar, but
in everyday use as South Great George's Street etc.
