Thank you for all the information.
I replied straight away to your question of "Did the family move away from Ireland", But unfortunately I do not see my reply posted and I fear you may not have received it?
The family appear on the 1881 census living in Johnstone Scotland. They have though changed their surname to Norton. Only Thomas Norton b. 1875 Ireland, my husbands grandfather, is at home with his parents. Their eldest son is on a later census as Robert Lurton Norton. I have never been able to find a birth record for Thomas.
It appears that there was a big exedous from Ireland as also in Johnstone are Nancy ( nee Gibson) parents Thomas Gibson and Dorethea Kant Nancy's brother Samuel Gibson and his wife.
It's looking very much as if the Lurtings/Lurtons were military people as Wm Lurton has on his marriage cert' of 1868 that his father James Lurton was a solider and if, as I am beginning to believe, the James Lurton b. Magilligan 1782 was his grandfather, he was a Chelsea pensioner. WO97.
I did write to Bobby Forrest after hearing he had written a book on Scots/Irish origins and he informed me that the Lurtings/Lurtons were a small clan. He also told me that the C of I Tamlaghard (Derry diocese) records are on Microfishe in PRONI BAP 1817-18 1831-9 MAR 1820-6 1832-4 Burials 1824-9 1832-4 1837-44 1844-1961.
Do you know if the Mormon Chruch would have a copy of this Microfishe? If they do, I could send to Salt Lake City for a copy to be sent to the Wellington Genealogy Department , where I could then go and look at it.
Thank you so much for your help
