I am looking for information on William Martin (1791-1870). In 1827 there is a baptismal record on Aug 29 1827 from St. Mary's, Abergavenny, Monmouthshire for his daughter Isabella. It lists William's occupation as 'servant' and abode as Beaufort Iron Works. I cannot find a census nor a map that would explain this information. William's wife is Margaret Creighton (1801-1874) and they also have a son John G. Martin born 1824, a son William J. Martin born 1830, and a daughter Marion born 1832.
Many thanks for any insight,
