I now know that my 3x great grandparents were :
Henry HITCHINS born Marros, Carms. 1799.
Mary, born Eglwys Cymmin c1805.
Their eldest son, William, was born at Kiffig c1823. He was my 2x great
grandfather. He married Ann REES born Amroth 1823 to Charles and Mary.
One of their sons, Henry HITCHINS, born 22.1.1862 at Amroth, married my
great grandmother Elizabeth PHILLIPS of Pembroke.
My 3x great grandparents Henry and Mary, had another son, Henry, born
1839, Crunwear. In 1881 Henry was at Pountglas, Crunwear, with his wife
Fannie, born Swansea c1836 and 4 children. Also living with was his
father, Henry, born Marros, 1799, widower.
If anyone can connect to this particular line I'd be pleased to hear
John Griffiths of Milford Haven.
