Sorry to throw a spanner in the works, but that's fully correct. Quite a few years ago, I got my gg grandad's birth cert & found that it had the time of birth on it. I actually phoned the register office to ask if he was a twin, they searched the index & found that he wasn't. The man I spoke to said that SOME registrars put everything they could think of on a certificate, whereas others just put the minimum. So - the time of birth does not always indicate a multiple birth. Pat.xxx :o)) A Maid of Kent This info is from Barbara Dixon's Certificate Tutorials - If there is a time against the date of birth then there was more than one child born alive at the birth. If one was alive and one stillborn, then the live twin will not have a time against the date. It is possible to check for twins by looking for identical or consecutive GRO references in the indexes. If the child lived for only seconds, there should still be a register of the birth and the death, though this was not always done.
