Cailean mac Donnchaidh

Cailean mac Donnchaidh ("Colin, son of Duncan") was the son of Donnchadh, Earl of Carrick († 1250), and brother to Niall, Earl of Carrick († 1256). If it were not for the culture and priorities of the contemporary Scottish monarchy, the chances are that Cailean would have become Earl after the early death of his brother in 1256, but in fact, his brother's daughter Marjorie of Carrick succeeded. Cailean's most important legacy thereafter was probably his daughter Afraig, who married Gilleasbaig of Menstrie, a Clackmannanshire baron who was the first attested man to bare the surname "Campbell". With this lady, Gilleasbaig fathered Cailean Mór, the ancestor of the later Earls of Argyll.
