Following on from my research of Sarah ALLEN, I turned my attention to Fanny ALLEN, another daughter of John ALLEN and Fanny ALLEN (née Fanny LITTLEWOOD). A search of FreeBMD returned a marriage in 1886 for one Fanny ALLEN and one George HILL. Unfortunately this date is too late for the England and Wales Census 1881. So using FreeCEN, I performed a search for George HILL on the England and Wales Census 1891. This found a record for the household of George HILL at Wilson's Yard, Saxilby, Lincolnshire, England. The birth place of Fanny HILL (née Fanny ALLEN) the wife of George HILL is recorded as Little Gringley, Nottinghamshire: Walter HILL the eldest son is also recorded as being born at Little Gringley, Nottinghamshire.
I think it is safe to assume that I have the correct Fanny HILL (née Fanny ALLEN) together with her husband George HILL. I can now add a few details for another of the ALLEN sisters.
