In 1768 Thomas Blackett married Ann Rowland in Hexham, Northumberland. Their son John had at least four sons: John (who was the father of Hudson Blackburn Blackett, formerly held as a separate tree), George, Thomas and William. William moved to Liverpool, Lancashire, but some of his descendants eventually settled in County Durham. We have not so far discovered a baptism for Thomas senior.
