Monica
What you are saying makes a lot of sense.
your reference
MACCOEL: A family named McCoel, McCeol, or McKoel, seem to have pronounced their name McCoal."This name and its varied spellings occur extensively in the Lochgoilhead Parish Records from 1695 to 1770, when it ceases altogether. It was at one time common in Kilmorich Parish.
This would explain why the name Agnes McKeol has dissappeared. I have found that it is a Sept name from the MacNaughtaon clan , so it is possible that that name was adopted by the family in later years.
In the familysearch link you have also provided me with siblings for our Margaret . I will have to check with my collegue who has a James Campbell with father Duncan Campbell and mother Nancy Naughtan , i think from his death certificate his birth date should be 1773.
Congratulations you have provided me with a glimmer of light on this family.
