I feel that by tracing them and putting them on my tree they are not forgotten.Jan, I do the same. I've been surprise to find how upsetting the discovery of infant deaths in the family is, even a century or more later. The first I found was my gr.gr uncle, several years ago, and the most recent I found last week explained my gr.gr.grandmother's early death: she died following childbirth and her son died at the age of 9 months. I record all of them on my tree for the same reason as you and several others do, and as I put together the family history for my children and grandchildren they will all have their place. Linda said that marks the difference between family historians and genealogists, and I think that's spot on.

As a point of interest when a death is registered and it gives no name for a neo natal death would that always mean no name had been chosen or just that the baby had not been baptised
are we we too soft now
Is the 1911 census available in Scotland yet? It might be that she is on it under a different name. Maybe her father couldn't cope after his first wife died so she was sent to relatives, (?in England maybe) or put into a children's home which often happened.

ps. If you give us Williamina's surname, you never know what Rootschatters may turn up.
It could be a red herring, but as she had such an unusual name, I did a search on FreeBMD (which doesn't cover Scotland of course) and came up with:
Dec 1917 Plymouth 5b 604 a marriage between a Williamina Robin to a Ralph Leddra.
Dec 1920 Plymouth 5b 366, the birth of a child Yvonne H G Leddra, mother's maiden name Robin.
I can't find anything after that, so maybe she moved back to Scotland.
