I am looking for any info, guidance and help on my Campbell ancestors. I know my great grandfather, Donald Charles McGregor Campbell (1861 - 1936) was born in Ardchattan, Argyll, Scotland and died in London, Ontario. His father was also Donald Charles McGregor Campbell (1815-1888) was born in Kinloch Rannoch, Fortingall and died in Rhugarve, Barcaldine. His father was Duncan Campbell believed born about 1776 but location unknown. Duncan's father was John Campbell. John's father was John "Iain Og" Campbell. Father of John "Iain Og" was also John. Father of this John was Donald "Bahn". Father of Donald "Bahn" was John "Dubh" Campbell. All names past my great grandfather is taken from his will. It appears that the names used follow Scottish tradition which means that my ancestors were probably the oldest male child in most cases. I do not know the name of the ship that brought them out, where it sailed from nor the date of emigration. I have been able to locate some descendants of my great grandfather's siblings in Canada and the US but no one know any more beyond the information above. Can anyone help me fill in the blanks regarding spouses, dates, locations, etc.?
