I hate to pour cold water on your hopes, but given that the Clan grounds were just to the South of Inverness, I reckon that you could find a good few that were completely unrelated! Anyway, I'll chip in my Lachlans, although I would caution that I don't have a great deal of faith in the completeness of Parish records from around that time, so I could be barking up several wrong trees!
Lachlan McBean m. Christian MacPherson with William (1738), Margaret (1745) & Lachlan (1748) in Holm, Croy & Dalcross (just beside Inverness).
Lachlan (the son) was a vintner who married Agnes Sommers in Edinburgh in 1771. I have seen his name spelt Lauchlane and McBane on some records. They had a son, Lauchlane, on 24th March 1772.
William (now McBain) married Elizabeth MacDougall and was Chairman of Old Greyfriars Parish in Edinburgh. They had a son, Loughlane (or Lauchlane, or MacBain), who married May Melville in Ceres, Fife in 1793.
If anyone can link to these or confirm/deny anything, please let me know.
