Woolley family tree

I am looking for birth place of a man born in 1774.  In Anchestry I have found 3 possible places.  Bliston, Stafford; Derbyshire; and Lenham in Kent.  We are planning on coming to England in September and see what we can find.  Are there records offices in each of these counties I could contact?  Or churches in those places I could contact?  Thanks for a reply.  

Prior to 1837, BMD's were recorded and kept in Church of England parish records. Because the records were being kept by assorted vicars, some of who were very good, others less so, the government took over the record keeping. Of course, there were non- conformist records as well if the family might have been Methodist for example. If you have only a partial idea where your Woolley family came from, it could be a daunting task to find them. George Woolley was a fairly common name which could possibly appear under other spellings such as Wooly, Wooley if a family member was illiterate, so the vicar wrote down what he thought was correct.  

On marriages, a woman's maiden name wasn't considered too important and could be left out altogether. It might say in the parish records, for example, 23 June 1789 George Woolley married Sarah, giving you no idea who Sarah was. Farmers were usually known as yeoman in records such as wills. I.e. I John Woolley of the County of Kent yeoman, hereby......

Even narrowing it down to three counties, still leaves a situation to determine which is the correct person in your family. You have to consider every tiny clue of known things that might give you the correct place.
