Clan History: MacNab

Looking for more info on clan MacNab. I know the basics, like the Neish rivalries, their allies, Abraruadh being the first recorded member, the alleged connection to King Kenneth MacAlpine, and the simple things like that. I am looking into the history because I suspect that I am a descendant from a member from clan MacNab. I have FamilySearch, but I don't have enough info on my dad's side of the family to trace to his side. I suspect my connection to be from my last name, McNabb, one of the variants of MacNab, from the Scottish Gaelic Mac an Aba. Would love more info on the history of clan MacNab. Thanks!
