Commentary
Stewart Baldwin says his mother is uncertain

Baldwin: 'I am less confident about the documentation of the ancestry of the Scottish kings back to Fergus than I was at the time I wrote the Henry Project pages on them. Some modern authors have expressed skepticism about the pedigree of Kenneth son of Alpin (e.g., Woolf, in his recent history of the period, "From Pictland to Alba, 789-1070"), and while I believe that this skepticism goes too far, they make some good points. In fatc, when I wrote the pages, I indicated that the documentation for this line in the early eighth century was far less than ideal. ... Also, Fergus himself is not strictly historical, but can be regarded as probably reliable tradition, and the first member of the line who can be considered as "historical" with confidence is his grandson Gabran.'. soc.medieval.genealogy ( https://groups.google.com/d/msg/soc.genealogy.medieval/Dqci_SC0GH8/MBkNDGiTMQAJ ), April 26, 2016.
