While I do not have news of Daryl's family's Edmund, I have a feeling that I should post the below information for a Nugent family from an East Clare location, re-settled in central New York State. There are five townlands named Caher: three in the civil parish of Feakle, one in Ogonelloe civil parish, and one in Inchicronan parish. Perhaps this can be of some use. The mother Mary's maiden name was more usually spelled Hines or Hynes.

TOWN OF ORLEANS
Martin Nugent and his wife, Mary (Hinds) Nugent, immigrated to the United States in 1851. They had three sons and three daughters, viz.: Nora, Edmund, Kate, Andrew, Maria, and John. Edmund was born in Cahar, County Clare, Ireland, in 1836. He also immigrated to the United Sates, in 1855. October 7, 1861, he enlisted in Co. H, 1st Lt. Art. N. Y. Vols., and was promoted from the ranks to sergeant. He participated in the following battles: Williamsburg, Bottom Bridge, Savage Station, Fair Oaks, White Oak Swamp, Malvern Hill, Mine Run, Laurel Hill, South Anna River, Spottsylvania Court House, Jericho Ford, Bethsada Church, Petersburg, Weldon Railroad, Poplar Grove Church, and Peeble's Farm. At the latter battle four of his cannoners were shot and his gunner severally [sic, severely] wounded, which threw the greater portion of the work upon Mr. Nugent. He suffered severely from exhaustion in this battle, and near Alexandria, Va., was severely hurt about the back and shoulders by his horse falling upon him. He was discharged near Petersburg, Va., October 16, 1864. In the fall of 1883 he became a charter member of the Grand Army of the Republic, George W. Flower Post, No. 306, of Theresa, and is now a member in good standing. In 1867 he married Eleanor, daughter of the late John S. Graham, of Orleans Four Corners. In 1877 Mr. Nugent bought the Graham homestead, and in 1884 built a fine residence thereon.
