There is a Sinclair tree on-line http://www.sinclairgenealogy.info/sinclairs-tullyroan
which says Harriette Jane Lawson married a Frazier of Blackwater. She was the daughter of William John Fowler Lawson and Adelaide Sinclair of Tullyroan. Her brother Simon married Rachel Cully in Belfast and widowed Rachel moved to Hamilton, Ontario with her father Joseph in 1898 with 3 children. Joseph Cully and Dorothy McCleary of Lurgan, Co Armagh are my distant relatives.
