I am a local historian, a native of and living in Crusheen. There are two separate issues here which may or may not be linked.
1. The Timothy McNamara query by Michael and
2. McNamara of Carhunacloghy info request by Gary
1. Michael points out that Timothy McNamara, his ggfather was in Sixmilebridge in 1850, married there and then came to a farm in Crusheen owned by the Castlecrine Butlers.
The major part of land owned by the Castlecrine Butlers in Inchicronan (Crusheen) parish was situated in the opposite end of the parish (to Carhunacloghy), i.e. in Toberbreeda Electoral Division. They also owned some land at Carrownacloghy and Carrowkeal townlands where the McNamara’s mentioned by Gary were tenants. I have had a look at my notes on the Valuation Cancellation Books for Toberbreeda ED. I have a record of Timothy McNamara as tenant of a holding of 117A 2R 16P (Map Ref 1) in the 1893 Cancellation Books in Knocknamucky Townland. He did not appear in the original Griffith Valuation or the cancellation Books of 1859 when the tenant was a Patrick Culligan.
This holding was the centre of a major dispute in 1900/01 when a local man, presumably Timothy McNamara, was evicted (by Butlers of Castlecrine) and an agent named Carroll was sent to run the farm. Carroll sent his children to the local school in Drumbanniff (Drumbonniv) resulting in 30 children being withdrawn by their parents in a boycott of the school. The only children attending the school for an approximately 18 month period were those of Carroll and the teacher Francis Enrick. I had never heard of this school boycott until I came across references to it in National Archives while researching an article on education in the parish.
The fact that there was such strong local agitation would indicate that McNamara may have had local connections. Unfortunately no Baptismal or marriage records exist for the parish prior to 1860 and 1864 so establishing relationships is going to be quite difficult.
However, Timothy appears to be a name synonymous with Michael’s family. I then checked for a McNamara family with the name in the area and discovered a Teady McNamara married to an Anne McCarthy in Cullinagh Townland. ( this is in Crusheen ED only a short distance from Carhunacloghy, but in Kilraghtis parish). Teady married into the McCarthy holding of approximately 7 acres and the likelihood is that he was from a nearby townland. Teady died, aged 70, on 16/12/1893; Anne died aged 56 on 28/4/1905. They had five children, Henry, bapt. 24/5/1874; Timothy, bapt. 19/2/1876; Elizabeth, bapt. 14/4/1878; Daniel, bapt. 31/8/1879 and Margaret, bapt. 13/9/1880.
Timothy married a Margaret McNamara , of Carhunacloghy a daughter of John McNamara Carhunacloghy and Bridget Galvin of Knockaclara (Kilraghtis parish) on 6/6/1914. Margaret was baptised in Crusheen on 20/11/1896. Her parents John ( bapt 10/9/1866, FN Pat , d. 14/1/1910,aged 85), MMN Bridget Casey) and Bridget Galvin (FN Denis) were married on 8/2/1896. Margaret had at least eight siblings and some of their descendants still reside in the locality.
If there are any of the above first names common in Michael’s family, this could be an indication of kinship.
2. Gary has outlined some of the names in his McNamara line. His ggfather Martin married Mary Casey on 27/7/1889. According to the local records Mary was a daughter of Patt Casey and Catherine Howard. She was baptised in Crusheen on 14/2/1866. Catherine died, aged 75, on 4/5/1914.
Martin and Mary’s children were:
Michael Joseph, bapt. 20/11/1890; Thomas, bapt 14/12/1891; John, bapt. 19/5/1893; Martin, bapt. 21/2/1895 and Pat, bapt. 27/9/1900.
His ggfather, Martin, had siblings Mary, bapt. Nov 1860 and Bridget, bapt. 13/1/1863. Father Michael, mother, Mary McGrath.
The John McNamara at 1 above who married Bridget Casey in 1896 is very likely closely connected to the Martin McNamara who was married to Mary Casey. John and Martin are probably first cousins and Mary and Bridget also likely to be first cousins. However those links need further confirmation.
Paddy, you may be able to clarify the Casey connections.
On the McNamara side there is a possibility that Timothy, Michael’s ggfather born 1815, if he can confirm the link to Crusheen, Pat born c.1825 and Gary’s gggfather Michael, born c.1826 were brothers.
