I was doing some work a couple of years ago on the children of Jeremiah Martin (1871-1946) and Roseanne Coyle (1877-1947) of Ardboe and County Mayo, and I surmised that Jeremiah was a son of Thomas Martin and Sarah Anne O'Neill, and thus a brother of Rachel, Agnes, Ambrose, Julia, Mary Ellen. I also reckoned that the Sarah Jane who married Francis Quinn in 1902 was also a sister, although her baptism is not in the Ardboe parish register. However I didn't check out this family. I don't think the Thomas Martin family lived in the Moortown area of Ardboe parish; possibly Brookend and Trickvallen. There is only one Sarah J Martin in the 1901 census for Ardboe parish - see Munterevlin/Kilmascally/home of Robert James Corr, where Sarah J Martin was the servant girl. That would possibly explain a Moortown connection.
