Hi Marcie Dean
just a wee bit of info. the term 'Laird' generally means the owner of a property e.g. farm etc.
From the early 1100's Argyll and the Isles (the ancient kingdom of Dalriada) was controlled by the Irish/Celtic Prince Somerled and his sons. His eldest son Dougal - progenator of the Clan MacDougall (some say this Clan is the oldest Scottish Clan - being a MacDougall who am i to disagree!!) inherited northern Argyll on the demise of Somerled. Somerled's second son, Reginald inherited southern Argyll (including Kintyre). I'm unaware of any O'may control of these areas unless it was Pictish prior to Somerled.
i have also found an interesting site regarding Keil Cemetry at Southend, Campbeltown:

hope this is helpful
