Frederick Blackett was born in Hull in 1821/22, the son of Thomas Blackett and Emma Clarkson, who married in Hull in 1819, but had moved to County Durham by the time of his marriage to Sarah Watson in 1841. A number of Frederick’s descendants settled in County Durham but his second daughter, Ann or Anna (1844-1913), married Henry Flounders (1836-1904) in 1866 and emigrated to Ohio, USA between 1876 and 1879, where some of their descendants live to this day. Through the marriage of a descendant this tree now forms part of the Main Tree but for a descendancy chart of Thomas Blackett and Emma Clarkson please click here.
