Just to give some ideas for those who wish to help

The naming patterns that John and Louisa followed when naming their children is interesting.
The first male was called William and apart from Johns brother being called William I don't have any strong idea why. Johns father is Richard and Mariah (Gill) Clayfield father is John.
Jane is the next child - first female died as an infant
Followed by Albert then John who both died as infants
*****^^^^^^^^******** All born in Gloucestershire
Arrived in Australia 11 Oct 1858 on the Bee sailed from Liverpool - The following emigrants are sent out on remittance ??
Maria - obviously for mother - who married my GG Grandfather
John again
Martha who is Marias mother
Louisa after Louisa Westm*****
Elizabeth is next ...maybe after the Elizabeth above
Finally we get to a Richard who dies as an infant
Elija Richard
Albert Leonard
And last but not least Johanna Matilda Alice Ann Clayfield when Louisa was either 45 ( marriage document) or 48 if we accept she was born in Ashley in 1827
Hopefully that gives some clues which way to go.
Ann could be a reference to Johns sister
