Denise, I have some information. I also am a "Duerden" family tree finder". Hartley's parents were Francis and Elizabeth (nee Hartley). Married in Col;ne 30/7/1832. Someone who is following the same line is Debbie Botham (firstname.lastname@example.org). Please contact me as I'm collecting a large database of "Duerdens" and all info you have I would be interested to see a copy. Regards, Ray.
