Barber family in Sheffield

In the 1911 census for Sheffield my g.grand mother Rose Flowers, age 18 worked as general servant (domestic) for John Barber, age 29, Departmental manager (Engineering) and his wife Elizabeth, age 28. They lived at 76 Crimican Lane. John Barber was born in Shoreham, Sussex and his wife was born in Sheffield. I would love to know more about the Barbers.

Thanks, Mary
