Hi Rosie
In 1962 while a schoolboy I did a grocery round for a small grocers shop (Merrimans) in Harleston Road, St James, Northampton.
Just up the road from there was a home for unmarried mothers, it was on a corner with I think Holyrood Road. It was nearly opposite to Spencer School.
I do not know much about the place as it was always kept as a secret from me.
I hope that helps
Peter
