Wales

Trying to find the parents and the birth date of my great great grandfather born in 1826 in Swansea? Wales. His name, Thomas B. Lloyd. All I know is that he was a coal miner and he lived in Maryland for awhile, where his first born son was born in 1853. Then he was in Pennsylvania when the next four children were born, 1857-1864. More children were born from 1866-1873 in Ohio and he was still living in Ohio when he died.
His wife was Winnifred Evans Lloyd born 2 Feb 1831 in Wales and died 8 April 1892. I also need Winnifred's parents name if anyone can help me out.

Just found this group and hoping this will assist me in my search that seems to be my brick wall currently.
