Searching the England and Wales Census 1881 I discovered Ziller JACKLIN (née Ziller ALLEN) 1858-1949, my paternal great grandmother, appears to have had an older sister Jane ALLEN 1853-, both were born at Little Gringley, Nottinghamshire.
I surmise Jane ALLEN 1853- married George SMITHSON 1830- of East Drayton, East Retford, Nottinghamshire since the 1881 British Census records Ziller ALLEN 1858-1949 living (as sister-in-law) at East Drayton in the household of George SMITHSON 1830-:

These records suggest Jane SMITHSON (née Jane ALLEN 1853-) had 2 children, either from a previous marriage or 'out of wedlock'. I will need to conduct further research.
