If you go to cumberlandroots and on the first page "parishes not on IGI" you will see that Dean and Brigham should be listed for the dates you want. However when you search for Ann there is only 2-8-1801 for anyhing alike in Dean to John and Jane (ignore the other one as it is a submitted record). With a parental search there are no other siblings born in Dean ( maybe in surrounding parishes) to this couple.
Oh I see I've been beaten by Geoff.
