Margaret Cameron Gordon Robertson, Perthshire & NS

Can anyone out there provide more detail on Margaret Cameron Gordon Robertson?

My g-g-g-g-grandfather was Charles Gordon, farmer at Carrick, near Fincastle,in the Parish of Dull.He married Margaret Cameron on New Year's Day, 1761.Following Charles Gordon's death, Margaret Cameron is reported to have married a Robertson and emigrated to Antigonish, Nova Scotia.

Her oldest son was my g-g.g grandfather Donald Gordon who was born September 24, 1762.He married Christina Maclaren, daughter of James McLaren of Invernenty.They emigrated to Prince Edward Island in 1803.His younger brother was John Gordon born 1766 whose son, Rev. Daniel Gordon, emigrated to Ontario, and whose grandson was Rev. Charles William Gordon, better known as novelist "Ralph Connor."A third son, Peter, born 1768, was ancestor of a line that stayed in Perthshire.

In the 1803-1903 Centenary Celebration and Unveiling of Monument to the Memory of the Brudenell Pioneers, Brudenell Island, July 16th, 1903, Margaret's birthplace is given as Inverness. J(ohn) M(alcolm) Bulloch in Gordons in Perthshire As Pioneers to Canada.Perth: The Munro Press, Ltd., 1930, while aware of the Brudenell pamphlet, found information giving Margaret's birthplace as Edintian, Parish of Dull, which is just a short distance from Carrick.
