Edward Sewell of Moordyke, Dalston 1774-1839

Researching Sewells of Dalston..noticed Wallace Ross member is related my 4g.g.grandfather Edward was probably Jane Sewell's brother...since posting my thread I have traced back the family through Wills and court rolls to transfer of copyhold title from John Sewell to his brother Robert Sewell in 1715. Any information to enable me to trace and connect back further would be appreciated
