I like the Clan Mackay Society USA membership requirments .....

"Joining Clan Mackay is easy. Simply choose if you would like an individual membership or a family membership" Membership dues are payable each year and are $20.00 (USD).

For more info please go to ... http://www.clanmackayusa.org/

That is it ... no offically researched Mackay Clan connection necessary.
