Hi, Ann,
You need to decide first, do you want to look for the PR record or the civil registration? The civil certificate will cost you £7, so if you can get to the
Bristol record office to search the Bedminster records that will be saved. But otherwise try FreeBMD or the civil BMD indexes at your local library, record office, LDS centre or at the FRC in
London, then order the certificate. The 2 sources ought to give the same information, so its just a matter of ease and cost. And, of course, in the PR you get the original signatures, not a copy.
