I have been in touch with Paul, he will look into finding out some details and will let you know.
However, as a starter, the Hibberts were from Buckinghamshire - Chalfont Hall (think thats how it is spelt), Sir William Hibbert. Frank & William came from Buckinghamshire to Sheffield at the start of the Industrial Revolution.
Hibbert Bros was started in Fargate in 1834 and moved to Surrey St
they married two Marple sisters from a steel family.
Will have more info soon.
