As far as I can tell, most of the Clocker families in this part of PA are descendents of Richard Clocker and Margaret Morgan. Richard was born 6 September 1824 in Llanbadarnfawr, Cardiganshire, Wales. Margaret was born about 1824 also in Wales. She died 15 December 1866 in Goginan, Wales. Richard came to the US around 1869 or 1870. He brought his children with him. Richard was a mining supervisor.
Richard Clocker and Margaret Morgan had 8 children that I know of. They are:
Jane Clocker, born 30 January 1844 in Wales
Elizabeth Clocker, born abt 1846 in Wales
Edward Clocker, born abt 1849 in Wales
Richard Clocker, born abt 1851 in Wales
David Clocker, born January 1856 in Wales
Morgan (male) Clocker, born July 1857 in Wales
John Clocker, born abt 1860 in Wales
Margaretta Clocker, born December 1863
I do not know when Richard Clocker died. I do know that he was in White County, Arkansas in 1880. That is the last I have been able to track him.
