Hi,
A couple more possibilities. In Dec 1869 a Mary Ann Scullion was born to Patrick Scullion and Ellen McVey. The birth was registered in Portglenone.
The 1841 census shows a Charles McCurley 35 and his wife Bridget 33 with two children, Margaret 4 and William 1 living in the townland of Longmore in the parish of Skerry. I have no way of knowing if there is any connection to yours but they may be worth tucking away.
Regards
