Hi,
I share common ancestors with Christina MacLennan, Joseph Lamont's wife. She is a descendant of the Kinlochewe MacLennans (mostly sheep farmers), daughter of:
Murdo MacLennan, b c1799 d 13 DEC 1860 in Inveran, Gairloch.
Grace MacDonald, b c1814 d 21 JAN 1885 in Kinlochewe Hotel, Gairloch.
The couple married 11 AUG 1847 in Applecross and appear in the 1851 census with 2 daughters (Isabella and Christina) in Heights of Kinlochewe.
Murdo MacLennan is son of:
John MacLennan, died 1817.
Isabella McGregor, b c1760 Gairloch d 26 MAR 1855 Kinlochewe Heights.
As for Grace MacDonald, I haven't completed my research, but she is from Applecross, daughter of Donald MacDonald and Catherine MacLennan. She had at least one brother, Lachlan (b c1835 d 27 JAN 1878 in Kinlochewe Hotel); he was an hotel-keeper.
Best regards,
Francisco
