I know little about Ann. She married Alfred Rue in 1940 and they had two daughters, in 1941 and 1950. They appear to have lived in the Neath area throughout life.
I do not know where she came from or anything about her family – to be honest I haven’t looked – with a name such as Williams this will be difficult, although not impossible.
It is possible that Ann died in 1997 – a Annie Mary E Rue did die in the Neath area then, but whether this is the same Ann has not been conclusively shown.
