Hi William, I believe that my ancestor Michael Smith of FALTAGH was one of the clustered Smiths you are researching. Michael was married to Ellen???. They were resident in Faltagh, AGHABOG Parish in 1860. Some(all?) of their children Owen b.c1835, Patrick b.c1826 and Ellen b.c1841 came to Australia in the late 1850's and early 1860's, I believe that these children were all born in Faltagh. The 1858 Griffiths Valuation shows property owners as Michael Smith, Owen Smith and Annie Smith. The family name is recorded as SMYTH in Australia. Do we have a potential connection to the line which you are researching?.
