My 2nd gt grandfather was Patrick Burns (or Byrne) who, according to his immigration papers, came from "Glasmerlough" Monaghan, Ireland.I was never able to find that place name.The closest is Glasslough, Parish of Donagh, Barony of Trough.According to an old Topographical Dictionary, it was situated on a lake, and indeed Glasslough means "green lake."Has todays Glasslough absorbed the old Glasmerlough, I wonder? I'm looking for any information on Burns or Byrne families who would have lived there prior to the famine times of the 1840s and 50s. When Patrick arrived in the US he settled in the area of Northampton, Hampshire, MA and married on 6 Jan 1858 at Greenfield, MA, Delia Nally, daughter of John Nally and Maria Ellen Moynihan also from Ireland. Patrick and Delia had children: Maria b 1861, Helen/Nellie, b 1863, John, b 1865, George b 1867, Mary Veronica b 1869, Elizabeth b 1875, Arthur b 1881. I'd very much appreciate any information on the place names and/or family names.Thank you.
