My name is David Tilson. I am 31 years old from Dublin, Ireland. My ancestors are originally from County Cavan, Ireland. I have traced back as far as my great-great-grandfather Robert Tilson of Derrylurgan, Ballyjamesduff, Co. Cavan but wish to extend this further. My great-grandfather David Tilson was the youngest of 9 children - including James, John, Margaret, Martha, Frank and Anna. Some of these emigrated to the US at the end of the last century.
