John Griffiths 1806-1852 Master Mason and Builder died Trevethin and was married to MARGARET HARRIS DAVIES (1801-1880+) Previously he was married to Sarah Morris (circa 1805-1842) and had 8 children, who died of Typhoid possible parents john and Mary Elizabeth Morris.
Margaret Harris Davies Griffiths 39, from Marlybone London, married David DAVIES (1786-1842) in 1840 whose former wife was Elizabeth Jones (circa 1789-1838) Trevethin, who with Margaret his second wife, were noted as Inn keepers and DAVID DAVIES, a Brewer of the Three Cranes in Crane St ,Trevethin Monmouthshire in 1841 census .
Some of David Davies 13 children with his wife Elizabeth Jones were sent to live with her family in Trevethin but John and Margaret Harris Davies Griffiths adopted Elizabeth Griffiths later. Margaret later married William Phillips about 1865 whose wife had predeceased leaving about 12 children Margaret Harris despite having no children of her own was step mother to about 30 children
John Griffiths is indicated to be born on 1851 Census to be born in MANTWILL GLAMORGAN but this does not exist so am trying to find out what this place might be. His father was William Griffiths also a builder and possible mason from Glamorgan
His children were all christened in St Cadocs which appears to be overgrown now I suspect he may be buried there and as a mason he probably had made tomb stones for his family and others. Could you help me please me find Sarah MORRIS parents and also JOhn Griffiths parents and where they were born
