Jeremiah Hall - where did he come from?

I’ve been relooking at an old brickwall on my family tree this week.  My x 4 great grandfather Jeremiah Hall was baptised in Edenbridge in Kent in 1789.  He had a sister Jenny, baptised in 1781 and a brother, William baptised in 1787, both in Edenbridge.  Their parents on the baptism records were Michael and ______ Hall.  Very useful!  
A marriage for a Michael Hall in the right time frame has not been found and neither has a baptism of a Michael Hall.  The closest we have come to is a Miles Hall who married Jane Holiday in 1769 in Crowhurst in Surrey and went on to have 4 children, all baptised in Crowhurst; Sarah – 1769, Martha – 1770, William – 1773 buried in 1774 and Benjamin – 1775.  
I have spent 10 years picking away at this problem, and chatting with other people who are also trying to solve this riddle.
We know that Jenny baptised in 1781 married a Richard Holmden in Edenbridge in 1802, a marriage which has led to a further clue.
A will has been found for a Mary Ware who died in 1807 in Crowhurst.  She mentioned several family members.  She had previously been married to Benjamin Hall who had a brother, Michael.  She mentions three of Michael’s children; Benjamin, Sarah who married _____ Fowle of Westerham and Jane who married ______ Holmden of Edenbridge.  
So far that is looking good, Jane and Jenny, same person?  There is a marriage for a Sarah and a John Fowle in 1792 and Benjamin could be the one baptised in 1775.  
Mary Ware also mentioned a Nicholas, another brother of her late husband Benjamin who also had a son Benjamin. (What a popular name that was!)  So plenty of clues to help pick away at this.  But sometimes the obvious and most needed answer is just plain elusive.  
Could Miles and Michael in Crowhurst and Edenbridge be the same person or am I clutching at straws?  There is a family being baptised to a Nicholas and Ann in Crowhurst in the 1720/30s including a Benjamin, a Miles and a Nicholas but Miles was baptised in 1722 meaning he would have been in his late 40s when Sarah was born, never mind Jeremiah in 1789!
I will keep at this one and hopefully one day I will find an answer.
