Failing miserably with Francis Charles and Hannah Elizabeth so looked at one of the others for clues and Emily Lavinia seems to have ended up in Queensland Australia.

Judging by children's births on a family tree they must have left England between 1872-1874.

Maybe other family members went there too.

Thanks for looking Tourmie, it was not just me. Found a Francis Charles Williams on the census married to a Elizabeth, but her surname I am almost sure is Garland and although the birth year for Francis was correct the area was not.

Another brick wall.
