I am trying to find the birthplace of John Drewry who married Mary Sails[Sayles] in 1795 in Crowle. Their first three children[1796-1800] were born in Haxey And possibly two more in Doncaster[1809 and 1817].I have a number of clues pointing to his being the son of John and Martha[Johnson] Drewry of Haxey who was born in 1771. However I need to prove this. Any help would be appreciated. Katybee
