A way forward
might be to obtain the 1857 Birth Cert of Adelaide - see who her parents were - if they
werent the Chris' and Emma in 1861 census, then the 'Boarders' relationship is correct .... and you're back to Square one..... altho you will have the actual parents names to work with, which will help if the girls are sisters....
If it IS them, and the mother is formerly Dur(r)ant, then that marriage is correct.
And also safe to assume that Agusta / Amy was born out of wedlock, but at least shares one parent with Adelaide ....
