I just can't let go, can I?!
The GRO has the following marriages for a Gladys MOORES in the years 1933-1936. There may be more in other years. It could be any or none of them. The only way of knowing, as I see it anyway, is if someone with access to the original marriage certificate ordered a likely looking one and compared/saw if it says widow. But even if the right one was found - what then? Easiest for someone living in wherever Gladys settled to follow up. Either way, I think I'm done.
