Hello Yvonne, My Great Grandmother had either a mother or father by the surname Lavelle. Her name was Winifred she married Edward Finnie in 1881 (I believe his surname used to be Finn?). They lived on Achill Island, Edward was a school master there. They had 9 children: Annie 1882–1884, Catherine 1883–1981, Thomas 1885–1914, Edward 1887–1938, Delia 1889–1964, Alice 1891–1970, Ada 1893–1970, John 1899–1918, George 1906–1973 (my grandfather).
Does this fit with anything you know?
Would love information if you have any, although it looks like we are equally in the dark. Apparently all the records were burnt in a church fire on the island – makes it very difficult :) regards Kate Finnie
