I was thinking of the Vono that used to be on the Vaughan Trading Estate on the Tipton Road side. I remember the company being there in the 1970s, but whether that was just a show room or not I don't know.
When I was little, living on the Old Park Farm Estate, I'm sure one of my Aunts and our next door neighbour used to work there. There used to be quite a few women crossing over our green and I seem to remember them having to catch a coach for them to be taken to work.
Here's a map dated 1938, left hand side pretty much in the middle.

FMP has National School Admission Registers, but they would be too early for your Mom as the years are 1870-1914. Found my grandparents on there but not my parents.
