I have hit a brick wall and wonder if anyone can suggest a solution. I have a baptism for William Edgar in 1850 at Lower Machen parents Luke and Hannah Barnes but have been unable to locate a birth certificate from GRO or local offices. In census of 1871 William Barnes is in St. Mary's Barracks Watton Brecon as a Private aged 21 ... perfect age. There is a birth recorded in 1855 at Newport (which would be correct district for Machen) for a William Barnes, but without applying for the certificate I do not know if this is the same William. Could the certificate be applied for if parents forgot to register the birth in 1850?
