murphdog822 on Family Tree Circles

My 2nd Great Grandfather left Co. Kilkenny, Ireland in the late 1860s to come to America. He settled in Moore County, NC and married Mary Jane Williams, a native of the county. They later moved to Guilford County, NC where many of his descendants still reside. I am seeking information regarding the Murphy family of Ireland. I believe Thomas came from Gowran, County Kilkenny. Thomas Murphy (21 Dec 1848-26 Nov 1909) had according to my information, at least 3 siblings: Michael (b. 29 Mar 1842), Margaret (b. 28 May 1844) and Denis (b. 26 Aug 1846). I believe their parents were Patrick Murphy (b. Feb 1819), and Annie Fox (1823-1886). Any info prior to this generation is sketchy at best and that is what I am seeking. Any assistance would be greatly appreciated.
