Hi
I don't have access to baptism records and very few for Stockport are available in the IGI, none for Hannah Chadburn.
I would suggest you put a separate request on this board you may catch someone who's going to the record office.
http://www.rootschat.com/forum/index.php/board,205.0.htmlAs to marriages for Richard there are two, neither of which are to a Martha or a Dodge.
22/January/1789 Richard a weaver and Lettice Wilkinson at Stockport.
1/September/1795 muslin weaver and Ann Shelmerdine also at Stockport.
Just found a marriage which looks as if it may be the one.
Richard Chatburn weaver 25/October/1801 to Martha Harrop at Stockport by licence.
This where the Dodge connection seems to arrive
Martha Dodge married Robert Harrop 26/Nov/1774 at Stockport.
hope this helps
