Ancestry have the baptism and burial of Thomas Blowers Jay -then another baptism on 19 May 1818 -also Thomas Blowers Jay, parents Thomas and Sarah Jay.
It looks as though this may be the Thomas you are descended from, Teresa.
On the subject of Hannah Hambling -with your help Jay I was able to establish that she did marry John Goss, lived in Great Yarmouth,had 2 more children and died at the age of 65.
On the subject of Eliza Hambling-I also discovered that Hannah had an uncle named Noah. He couldn't have been the father of Eliza since he died in 1808-but Hannah also had 13 siblings/half siblings (her father outlived 2 wives and had a further 7 children by wife number 3!) It seems likely that one of them used the family name Noah -making Hannah Eliza's aunt.
