This page was formerly titled Martha Blackett and Henry Haigh of Yorkshire, due to the mistaken assumption that Henry Haigh had married a Martha Blackett, believed to be the mother of at least six children, including one, Rev. Joseph Haigh, who named his second son William Blackett Haigh.
Thanks to research by Ashley Haigh it has now been established that Henry Haigh married Elizabeth Blackett, the daughter of John Blackett of Skircoat, Halifax, and the granddaughter of Richard Blackett of Skircoat. Richard's parents have not been established.
Branches of his descendants settled in Lancashire and some in Canada and in Texas, USA.
