There is no separate Clan Donald Canada DNA Project, but Canadians, Scots, Irishmen, Australians, New Zealanders, and others can and have joined the Clan Donald USA Project, which reached the milestone of having over 700 members with results posted as of the most recent update of the project website.
The name Archibald McDonald sounds familiar. I may have seen him listed as the earliest known ancestor for one of the project participants on the Ysearch website. Ysearch is a free database sponsored by Family Tree DNA, which has done most of the testing for the Clan Donald DNA Project. Anyone with Y chromosome DNA test results from any lab may post them on Ysearch, and others can search that database by surname or by looking for DNA matches to their own results or to a possible set of results that they specify.
When I did a search for DNA results for McDonald men just now, I found 3 listings for men whose lines have been traced to N. Uist, and there were others whose lines have been traced to Inverness-shire. I looked at the 3 listings that I found for N. Uist, and I did not see Archibald mentioned, but I think that you might want to look at those entries yourself and also check out some of the others. The DNA results show that 2 of the N. Uist McDonalds are related to the MacDonald clan chieftains.http://www.ysearch.org/
You will want to look for variant surnames like McDaniel, Donaldson, Macdonald, and McConnell in your searches.
Once you find some interesting ysearch entries, you may want to look for those men on the DNA project results tables. By clicking on their Clan Donald codes in the tables, you can easily find their genetic matches. If they have Ysearch entries and the project webmaster knew about them when he was posting their results, then you can easily navigate to those entries by clicking on their Ysearch IDs.http://dna-project.clan-donald-usa.org/tables.htm
The project website has a lot of other useful information on its other pages. If your line is from the clan chieftains, you may find the History page titled After Somerled particularly useful. One man from the clan chief line told me about his ancestor from Kinlochmoidart, and I was able to find that ancestor's line back to Somerled using another MacDonald genealogy site that I believe is maintained by one of the other Clan Donald organizations. So information may be found in a few different places, even though there is just one Clan Donald DNA Project. It is best to have one large project, so that genetic cousins and project administrators can easily find each other and work together. Once researchers find their genetic cousins, they can work with each other in smaller groups.
If you have any questions, let me know. I'm curious now about Archibald, and wonder if he is listed as an earliest ancestor somewhere in the Ysearch database.
