I hadn't forgotten about your posting and have been looking around the area,
In 1811 there is an Edward he is yeoman ,death,from Torver,just down the road from Coniston and not that far over the tops from Broughton,his probate record is at Lancashire archives, I haven't found any thing else on him as yet,besides the fact I can find no further information on Sarah who is living with John and Jane and Matthew,
