If he was a glass blower this was the correct couple. Both living at  Kew St, Liverpool. She was a minor he was full age. His father was Thomas Sanderson, a glass blower and her father was William Wainwright, a book keeper.

Hello Rosie99 and Excel.
Thank you for your replies.
My great great grandparents were William Sanderson and Margaret Wainwright and his occupation was a glassblower so it looks as though we have the right family.  Brilliant!
They already had another daughter - Susannah Wainwright Sanderson - my great grandmother who was born 9.7.1847.
It is believed they had two other children William Robert and Isabella Kate who are thought to have both died in infancy.
Again thank you for your help it is much appreciated!
