Yes, very interesting.
I should perhaps mention the usual caveat about paternity details given by illegitimate children when they married. They are generally unreliable because people were often ashamed not to know their father and sometimes invented or embellished details to cover that up.
In this case however we know that he did not conceal his illegitimacy; the minister was aware of it and indeed struck out the information on that basis. He did not claim an imaginary Dowey father to match his surname. The "Lloyd" name rings true because of his middle name.
However it remains possible that he filled in gaps in his knowledge, so you may need to be open minded as to whether his father was really a John like him, or really a draper like his foster father.
Have you traced Eliza and what became of her?
