Comments on Duncan (Campbell) Campbell IInd of Glenurchy

Question

YDNA testing by the University of Strathclyde Glasgow along with the genealogists at the Strathclyde Institute for Genealogical Studies and the Campbell DNA Project have concluded that Sir Duncan is not the biological son of Colin Campbell 1st of Glenorchy. The press release of this finding was published October 2023 and is below.

The reason for my comment is that the YDNA test of one of the partcipants is on WikiTree (see above) and is propogating down unrelated Campbell lines like the Campbells of Auchinbreck among others making the WikiTree YDNA feature useless to genealogists on WikiTree and misrepresenting their work. A simple change to Duncan's profile marking his father as non-biological would fix this and keep the profile intact. This is a pre-1500 profile so not just anyone can fix this. So what do we need to do to update Duncan's profile? Do we need to provide something else from the Clan Campbell Society (North America), Society Genealogist, Jules Anderson, MSc, QG, FSAScot or from the genealogists at the Strathclyde Institute for Genealogical Studies? Looking forward to a timely response

The study has not necessarily shown that Sir Duncan was not a biological son of Colin, but rather has shown that the Glenorchy branch of the Campbells and the chiefly line (Argyll) do not descend from a common male ancestor. Where exactly the break was cannot yet be determined with certainty, but it is possible that the break is at Sir Duncan and Colin. It's also possible that the break is in the chiefly line. Sir Duncan is identified in primary sources as a son of Colin, though.

Edit: further detail provided below show my comment here is mistaken.

The Campbell DNA Project Team has used Y-DNA samples from other participants to narrow down the NPE, with reasonable certainty, to this likely generation.  The analysis is too detailed for this forum, but the Campbell DNA Team stands by this conclusion.

Yes, "with reasonable certainty," and "likely." Very important modifiers of the claim that "Sir Duncan is not the biological son of Colin Campbell 1st of Glenorchy." Discussion of this study needs to be incorporated into Sir Duncan's profile, as long as it includes the caveat that we can't be sure that is where the non-paternity event took place, only that it was approximately and probably at that generation. Further evidence may change how things look.

Can we get someone with the pre-1500 certification to add the following research note in the profile for Duncan Campbell-2352, and then set the father for this profile as non-biological? This will keep the Y-DNA under Duncan the 2nd from propagating above him in WikiTree.

== Research Note ==

The following press release explains how the Campbells of Glenorchy are not biologically related to the Campbells of Argyll within the timeframe of surnames, based on Y-DNA evidence. Additionally, the Campbell DNA Project Team has used Y-DNA samples from other participants to narrow down the NPE, with reasonable certainty, to the likely generation of Duncan Campbell, 2nd of Glenorchy. We have DNA signatures under Duncan's father [[Campbell-2358|Sir Colin Campbell, 1st of Glenorchy]] that match Argyll, but the DNA under his son Duncan Campbell, 2nd of Glenorchy matches the separate line as discussed in the press release.

Thanks for the further information. I was mistaken about just how much has been determined from this study.

Answer 1

Can any of the Y-DNA test takers add their Y-DNA information and mitoYDNA IDs to WikiTree?

One tester, a descendant of Duncan has added his test which propogated up to Duncan and then down again to all that have a connection. We need to break that connection at Duncan as he is not the biological son of Colin. This test should only propogate up to Duncan but not to Colin and non bological brothers.
