Michael Mcgill

Hi, I am still trying to find a baptismal record for my 2nd great grandfather. He was in the British Army and his pension records state that he was born in 1830 in Dungannon. I think he was Roman Catholic as I have made a connection with his son's family and their records are Catholic. I know of 3 children : Rose  Anne , according to UK census, born in Belfast, abt. 1850, Isabella, born in Fort Beaufort, South Africa, abt. 1860. John, born in Dover ( family say) in abt. 1862.I have looked everwhere for John's birth record, using the different spellings of Mcgill, to no avail.I have looked at the army records and births abroad to try and find Isabella's birth but again have found nothing.

I have scoured the Roman Catholic Parish Registers but again to no avail.

I dont know the name of Michael's wife or parents. I have used Irish naming patterns to hypothesise that his father was John and his mother Isabella Mcvey. I have found a marriage for them in Cookstown, 3rd Feb, 1825.

However I cant prove any of this.I have done lots of searching to try and be specific about townlands but with no coclusion.

I would be grateful for any advice you can give me about where to look next.

Many thanks, Ann
