The tradition of Clan Donald, from what I understand of both family and the Clan members, you normally wear the tartan of your Father's side, not your materal side. I asked this question here several months ago, as my Grandmother on my paternal side (MacDonald), is a Chisholm. I wanted to purchase a Chisholm Kilt to wear to honor my Grandmother side, but was discouraged from doing so.

I also have Macintosh, ( Paternal Grandfather MacDonald's Mother), Kennedy (Paternal Great Grandfather's Mother), other Paternal
wives maiden names, MacDonnell, Huet, MacDonald, MacBride, MacKenna and MacIsaac all married MacDonald from Lochaber and Knoydart, all Clanranald MacDonalds, going back to 1640.

So point that was made to me here and with other Scottish folks was you wear your paternal Clan tartan, not the maternal side tartan.

Cheers.
