Hello,
I have Miles Og MacMillan born about 1790 in Scotland, and he died May 2nd 1868 on Lot 30, Conc. 8, Lochiel twp, Glengarry co., Ontario. His father was John MacMillan.
I have a census for October 5th, 1830 and October 5th, 1851 that both Miles and his wife 'Peggy' were living at Lot 30, 9th concession, Lochiel township, Glengarry, Ontario, Canada.
Margaret 'Peggy' MacPhee b. about 1792 d. June 6, 1872
Miles and Peggy had 11 children. My lineage goes down through their daughter Ann/Nancy MacMillan b. Feb 5, 1814 d. Apr 15, 1840 (bu: St. Finnan's cemetery in Alexandria) she married Angus MacMillan b. 1811 d. 1878 (bu: St. Alexander's church in Lochiel)
Hope this helps!
Maureen
