I am the Great Grandaughter of Albert S Jeffery -
Born 1874 from Matlock Derbyshire and his wife -
Emma Jeffery born 1873 also from Matlock Derbyshire.
All I Know is they lived on Smedley Street, Matlock and worked for Smedleys Hydro.
Albert S Jeffery was the Head Billiard Marker and Emma did unpaid house duties at Smedleys Hydro.
They had two sons Albert Edward Jeffery and Wilfred Jeffery and a daughter (my gandmother) Yolande Louise Crowder)- not sure if they adopted her.
I'm now stuck on my research.
