Hi
I'm new here and I'm amazed at the information on offer. My maiden name was Mahon. Father Patrick Vincent Mahon (1926-2003) and mother Olive Elsie Dunn (1925-). I am having trouble locating Mahons as my grandfather was born in Wexford, ROI (1894), and came to this country to fight in WWI via Liverpool. His parents were John Mahon and Mary (Laughlin?

). How do I start to find my Irish ancestors, as I believe an awful lot of records were destroyed?
Any help would be appreciated.
