I have traced both harriet's from 1861 -both living in St Swithin's -one giving p.o.b. as Saxilby
Harriet b. Saxilby living in St Swithins -her parents are Jonathan and matilda
I don't think she is your harriet
This one seems more of a match -especially mary Robinson who was visiting Harriet and George in 1881 is Harrietts sister-also some of George and harriet's children have "family" names
Of course -the marriage certificate is really necessary to confirm harriet's father

I am wondering if harriet has ben mistakenly entered as Charlott on this census

I can find no trace of a daughter Charlotte with this family other than this year?
