Being a Harvey/Hervey I wear the Austin-Keith tartan. Our esteemed but not terribly involved chief prefers we wear the "ancient" pattern. My wife is an Austin and wears the same.
I also wear MacBain due to my close friendship with James McBain of MacBain.
I also honour my mother by wearing the MacLachlan and MacEwan tartans on occasion.
I plan of purchasing another Gunn "Ancient" kilt in honor of the re-established kinship between Gunn and Keith.
