Jonathan, Here's what I have.My family is from the C.28 (Auchindarroch/Brocks creek) McColls.John was the fourth son of Duncan McColl "Donachadh-ban-mor" or Big fair haired.
Duncan was born c.1725 at Auchindarrach, and had 2 wives.His first was Mary McColl from Glen Nachdrach(c.1730). They had3 sons. Duncan (1759-1822) who's son Thomas I'm descendant from. Johnwho died at 2yrs in Scotland Donald who died in Ontario. Mary died giving birth to Donald.
Duncan's second wife. Whom I only know was a Buchanan. Died with Duncan in Kilmelford.They had 2 children.
John who died in Ekfrid, Ontario. and had a son Duncan and daughters Mary and Catherine. unfortunely thats all I know on John. I have this information from My GGGGpa Elder Thomas McColl of Brocks creek. He wrote it in 1861. and Edith Durand McColl who did extensive research back in the early 1900's
the second child was Euphemia who married a McIntyre and lived in Northumberland County, Ontario.
hope this helps. I have alot on my C28 family. But have not been able to go back any farther than Duncan and Mary.If you have any information on my C.28 I would enjoy hearing about it.
