Seems as if its right Ellen. Still no info on Martha Gough's wedding to Galder but I have death certificate for him and Martha she married a William Jones (witness on Elens marriage) and they had a daughter Eliza 1849 - they were living on 1851 census in Monmouthshire. A witness to Marthas second marriage was Henry Whittington also from forest and he married Sarah Gaulder another of Marthas children in 1847 Brynmawr
I have a possible Ephraim (who also married in Monmouthshire) in the USA hope this makes sense Gill
