I have been following this amazing thread & well done to all who have found so much in such a short time.
Sorry, but I'm a little worried about the tree on Ancestry for the Fisher family. The time line that Ruskie has written out contains the 1881 census for George Fisher, Coal Miner aged 44 born Ilkeston, his wife Harriet age 49 born Cotmanhay & their daughter Harriet aged 7 born Ilkeston. living at 11 Charlotte Street. The 1871 has George, wife Harriet & a daughter MARY ANN age 10 living at Charlotte Street.
From Family Search there is a marriage for a Mary Ann Fisher to a John Scattergood 4th June 1884 at Cotmanhay. Her father was George.
I see another family on the 1881 for another George & Harriet Fisher with a daughter Mary Jane but they are in Nottingham not Ilkeston.

Would welcome other opinions please.
