I am researching the surname CLATHWORTHY from the Londonderry areas of Bellaghy, Castledawson, Magherafelt, Mullaghboy. JAMES BROWN born 1871 in Bellaghy, son of JOHN BROWNE and MARGARET JANE nee BLAIR named his youngest daughter ANNETTE CLATHWORTHY BROWN. ALSO SEAWRIGHT JOHNSTON and HENRY McERLEN were executors of the last will of Robert Blair who farmed at Mullaghboy and died c 1906-8. Robert left his property to his wife JULIA and sons GIDEON, ROBERT and JAMES. It interests me in my research for the possible connection between these families. TIA Val New Zealand
