Blacketts of Houghton-le-Spring, Cox Green, Penshaw and Sunderland
In 1737 Thomas Blackett married Margaret Carter in Houghton-le-Spring, Co. Durham, where at least six of their children were born. Their eldest son, John, (1740-1822) married Hannah Reed in 1774. John and Hannah had at least 11 children born in Cox Green and Penshaw, some of whom remained in the area, some settling in Sunderland and some moving some miles south to Sedgefield. A member of this branch, Thomas (1807-1878), a grandson of John, moved to London and then to Kent, where his daughter Elizabeth Jane Blackett married James William Rand and had at least 6 children.
