Hi Gaffa
There are 776 birth/baptism records of Mooneys in Kildare on www.rootsireland.ie/ (pay site)
The earliest is of a John Mooney in 1741; however there is no Moone parish in the list of parishes (click on magnifying glass at right of record).
The Tithe Applotments 1823-37 (free online) have 61 Mooneys in Kildare but there is no mention of a Moone parish there either.
Griffiths Valuation 1848 - 64 has 1 Mooney in Moone (attached)
Best results are on Family Search (free) which has 465 Mooneys (I searched for Mooney in Moone)
