I have two families of Irish ancestors who travelled to Wales and both ended up in Newport, Monmouthshire. I have been fortunate enough to build quite a family tree for both sides.
On Grandfather's maternal side: Fitzgerald = came from Cork (going back to 1829) and left between 1865-1868, first appearing on Welsh Census in 1871.
On Grandfather's paternal side: Murray as yet unknown location (in Ireland) of departure, as yet unknown date of departure, first appearing on Welsh Census in 1851, but GG-Grandfather born in Newport in 1845/ 1849.
I have read much of what they must have endured through their lives in Ireland; and I believe that is what helped them to survive the terrible journeys that they had to make to find better lives. I am in admiration of their hardiness and am thankful that they undertook this. Their drive is what has contributed to the good life of myself and their other descendents, and I'm proud of them for that.
