Here is the answer to your question!
Whilst plodding through some old notes I came across the following:
From Lillington Bishops Transcripts:
Henry Smith illegitimate son of Susanna Banger bapt 23 Oct 1836.
So Henry’s father may have had the surname Smith?
There is also recorded another illegitimate child’s baptism: Ann Hardy dau
of Susanna Banger bapt 19 Jul 1829.
The only Susanna Banger I have details of was the dau of George Banger and
Caroline ****, but she died in 1822 aged 9. So your Susanna could not have
been a second dau of George & Caroline because the birth of Ann Hardy above
would have made her aged 7 = impossible!
I am sure that there is more to tell somewhere in the records!
