Twins registered on BMD

[zetlander]

My aunt had quadruplets - all boys.  Two boys were born on May 31 and two boys on June 1. They were live births but all four sadly died shortly afterwards.  My aunt also died.  My uncle had the difficult task of registering four live births followed by registering the deaths of the four babies and his wife.
I think all four births were registered in the order of birth and the deaths in the order they died - which wasn't the same as the birth order.

My brother and I were born 2 hours apart across midnight, nowhere are we registered as twins

Your different birth dates would make it obvious which was the elder, so there would be no need to register the time of birth as is usual with twins.

I checked the marriages and found there was another couple in the same town with same surnames - they married just two years before my couple so definitely likely to be having babies around the same time. I also check in the 1939 and found my couple only have one redacted name so am now of the opinion it was just coincidence.
Thanks to all for your input and ideas.
