I am researching the Sewell/Sewill family in Knaresborough. The earliest I have is John Sewell/Sewill c1780 who married Dinah Spencer 10/03/1803 in Knaresborough and had the following children:

William 25/12/1815 ]baptised]
Samuel c1817
John c1823

William married Ann Langton in 1873 and had 7 children.

Any help would be appreciated
