Hi Adeline,
You may not read this as your post is an old one but I know your father`s umbrella factory. I was a friend of your brother (AJH) in the early 70`s and have very fond memories of your family and family home.
I visited the factory one Christmas for a staff party which was a very jolly affair. It was like a step back in time, a bit Dickensian.
I remember the staff you mention in your post and I recall that they idolised your father and I think referred to him as Mr Michael.
I also remember the person that made jewellery and in fact still have one of his stainless steel and abalone rings.
Your mum ran a stall at Bakewell market and I sometimes helped out selling umbrellas, bags and and purses.
Very happy memories.
