G2G: Any proof that President Biden's ancestor John Horn was the one born in 1706?

Question

I created a wikitree profile for President Biden's ancestor John Horn (who married at Childham, Sussex, in 1732).  Looking for solid proof he is the John Horn born in 1706 about 6 miles away at East Marden, Sussex.  He seems to be the only John Horn who fits (he is the right age and in the right area).  And furthermore, his mother Sarah (Chapman) Horn was baptized and married in Westbourne, Sussex, and Westbourne is also where John Horn's granddaughter Ann was married to James Biden.  The circumstantial evidence is very convincing that John Horn was son of Ralph Horn and Sarah Chapman, but how would one find solid proof that it is indeed the same John Horn?  I have a death date for Ralph Horn, but have no idea if he might have left a will.

And East Sussex  also

Answer 2

I have changed the burial date for his father Ralph Horn to 17 April 1726, East Marden, Sussex, England.  That makes more sense since son John was born at East Marden.  The 1714 burial date could be for Ralph's father (Ralph Horn Sr.).
