I tried to look for an Eliza baptised ~1809 at Campsea Ashe but with no maiden name it wasn't easy

There were 4 Eliza's baptised about this time and as I had time, I made a note of them in case they help in future. Of course none of them might be right:
Eliza d/o John Brook and Anne (late Elliott) born 27 Oct 1808 bap 9 Nov 1808
Eliza d/o Robert Crisp and Elizabeth (late Cook) born 29th Dec 1808 bap 7th May 1809
Eliza d/o Isaac Ling and Rachel (late Mann) born 11th Apr 1808 bap 7th June 1808
Eliza d/o Nathaniel Self and Sarah (late Knights) - also buried May 1809

Best wishes
