Regarding your comment about the 26 counties I believe that if you look at
http://griffiths.askaboutireland.ie/gv4/gv_start.php you will find a little more is added than that contained in Eneclann.
This is the address of the Ask About Ireland website that includes the Griffith's. It has been expanded to include Ulster, but as we have found out it does not have all of the maps in their data base. It does state that it is only a prototype/test site still under development.
To fill out the information on Catherine McCusker the following might be considered. While the information is not definitive, and most of the records available bare this out, it is known that a Pat McCOSKER (or McCusker) of Agharonan died in 1868. He did not have a will on file. Pat McCosker would have been born around 1813. And the name of the registrar’s informant indicates that there was a John McCusker in the family.
We do know that Catherine had a number of siblings: possibly a JOHN McCUSKER of Legamaghery, but little is known of him except that he was a single farmer. Another possible connection was Thomas M’GARRITY and JANE McCUSKER of Agharonan. There also was JAMES McCUSKER, an unmarried farmer who was aged 40, according to the 1901 census. That would have placed his birth about 1861.
Catherine married OWEN McCARROLL, also formally known as Eugene, “at full age." However, family oral histories have indicated that she was only 17 at the time of her marriage, and she was living at Legamaghery. She was married in Fintona which is also in the civil parish of Donacavey. They were wed on 25 June 1867 in my great grandmother’s Roman Catholic church at Donacavey (Fintona).
After her marriage she moved to her husband’s small farm in the townland of Corkhill (sometimes referred to as Corkill, as the years pass), where they raised their family. Corkhill is about 2 ½ miles south of Agharonan and Legamaghery and it is in the civil parish of Clogher, as well as the Catholic parish of Clogher at that time. It had a chapel within walking distance, in Eskragh (Eskra), which originally was part of the RC parish of Clogher, but broke off to become a parish in itself.
But, as is the case with most old Irish records, there is a discrepancy as she listed herself as a 60 yr old widow in the 1911 census, while the 1901 census indicated that Catherine was a 45 year old widow. That may be the result of the old age pensions law that went into place in 1908.
Owen and Catherine had at least seven children, all born at number 2, Corkill. All of the baptisms were actually located in the original church records in Clogher when viewed in 1982, but they were not found in the PRONI records in 1997. There is some discrepancy between the birthdates and the baptism dates, as recorded, for these children.
