Further to my posts above, I now believe that Thomas McGee did in fact come from the Killinchy area.  I still need to find his baptism, but have found the following -
William Magee and Grace had several children including James.  
James is Thomas' father and married Mary Moorhead.  They had several children including John and Thomas (who both went to NZ).
I have dates and some baptisms for many of these people; some of this info came from Presbyterian records from 1836.
My question to anyone is....... I am considering going to PRONI as I will be in Ireland next year (from Australia) but do not have much time.  I understand the Killinchy Presbyterian Church records are there on microfilm; I have the numbers from the guide.  It should be straightforward as I believe they were not non-subscribing Pres. 
Will it take me forever to find the baptisms of John and Thomas (approx 1841 and 1845)? I see there is and index to Pres Killinchy for 1812-1854, but then I would still have to look at the other microfilms of the actual entries.  I only have one day.
Anyone out there have experience of this ?
Thanks
