Garfiled on Family Tree Circles

I believe that John Rowlands was born in 1789 in Christchurch Newport Wales. He married Keziah Jones on June 7 1823 at Aberystruth, where she was born in 1790

John Rowlands was my Gt. Gt. Gt. Grandfather.

I have the family tree of the direct line of descendants to myself, from John b 1789 to Thomas b1829, to John b1851 , to Isaac b 1853 to James b 1881 and my father William b 1909

The earleir generations are centred around Rhymney S Wales

Can anyone help me research further back
