Florence Matilda Perry is living with George Henry Attlesey in 3 of the census, 1881, 1891, and 1901. She is described as his niece, which made me curious as to who her parents were. After some searching on both sides of the family I found she is the daughter of Hannah Curtis, Clara's older sister.
Florence was born in 1866 to William Reinold Perry and Hannah Curtis in London. She was baptised in Shoreditch St Leonard, London, on 25 Nov 1866.
In the 1881 Census, Florence is in Southery aged 15. Her mother is remarried to William Nunn with Alfred Perry with her.
In Dec 1907 Florence (aged 41) married William Edward Barrow (40) the older brother of Frederick Hubert Barrow who married Harriet Attlesey.
In the 1911 census they are living at Ferry Bank, Southery, and neice Nellie (aged 3) is staying with them. William is a Builder and Farmer.
William died in 1943 and Florence (Aunt Florie) died at Parsley House (home of Nellie and her parents) in 1950.
