MERGE WARNING: Extensive genetic research conducted by the Hamilton DNA Project Group has shown beyond a doubt that the subject of this profile is NOT the son of John Hamilton (Hamilton-1087) and so his father is shown as "Unknown".

As there are still a number of duplicates of this person in Wikitree if you intend to merge them then ensure that the details of his parentage are preserved and the notes refering to his genetic "fingerprint" are retained.


Who was the father of James?

Extensive research by the Hamilton DNA Project Group involving targeted genetic testing and analysis of historical documentation has shown conclusively that a non-paternal event occurred involving the first son of John Hamilton and Jacoba Douglas. The results of the Project Group, which has involved many hundreds of test subjects, can be found on the following site: DNA Project Site - Participants results

The Group A Hamiltons descend from either the brothers of Hamilton-1093 or his uncles giving a clear picture of the characteristics of John Hamilton's Y-DNA. The Group B Hamiltons descend directly from Hamilton-1093 himself which provides a clear picture of the characteristics of his DNA. There is no way that Hamilton-1087 can be the father of Hamilton-1093 and it is now known that the most recent common ancestor that they could share lived at least 4000 years ago.

At the bottom of the following page in Section 8 starting with the sentence "Who was the father of James? - (hyperlinked to James Hamilton, 5th of Cadzow)" you will find a discourse on the research project as well as an examination of the paper record of the time. Hamilton DNA Project Site - Paternity discussion

See also the notation under the "Paternity" section of his Wikipedia page for James Hamilton of Cadzow.

That note was placed in the early stages of the project and with the additional testing and research since then the matter has been clarified to remove any uncertainty. We now know that the real father came from a line that emerged genetically some 4000 years ago whereas the father's line, although on the same broad genetic branch, emerged about 2000 years ago.

Sir James Hamilton 5th Baron of Cadzow

History has him as the son of Sir John Hamilton of Cadzow and his wife, Janet Douglas however extensive genetic testing involving several hundred present day Hamiltons has shown this to not be the case (see the note further down this profile).

James Hamilton is first attested to in 1397 in a writ of that year, his father Sir John Hamilton granted him the lands and privileges of Kinneil, in return for the superiority of all property that had been promised to him through his marriage after his attainment of majority.

In 1424, Hamilton was one of the Scottish Lords allowed passage to Durham to visit the captive James I of Scotland in the same year, he was one of many Scots hostages given to the English as security for the payment of the ransom of the newly freed King of Scots his estate was valued at 500 merks.

Hamilton was confined first at Fotheringay Castle, then at Dover Castle. He appears to have been released by 1426 He was invested as a knight before 1430. Hamilton died not later than 1441, when his son is described as Lord of Cadzow.

Extensive Genetic Genealogy Research on Hamilton Surname

1. Extensive genetic genealogy research carried out by the Hamilton Surname Project indicates that contrary to popular belief, the father of the subject (James) cannot be John, the 4th Baron of Cadzow.

Genetic testing of numerous descendants of James has shown that he carried a particular genetic marker on his Y chromosome. This marker, an SNP (single nucleotide polymorphism), is designated L-1237.

Similar testing involving descendants of his father (ie his half brothers) as well as descendants of his father's non-lineal ancestors (uncles etc) has indicated that all of these males carry the SNP L-338.

As a result the is no way for it to be possible that John (4th Baron of Cadzow) to have been the father of James (5th Baron of Cadzow).

2 & 3) Rather than repeat the various volumes that have been written about him below are references to his Wikipedia entry and the Peerage.

DNA: Y-Chromosome Haplogroup


The FTDNA Hamilton DNA Project lists this person as a Group B Hamilton and so all of his male line descendants will also be in this group which currently has a terminal SNP of L1237. There have been several most recent SNPs discovered below L1237 which help define various lines of his descendants down to the present day.

  • Explanation of Y chromosome testing for genealogy purposes see Wikipedia
  • STR patterns can be used to predict a haplogroup, wheresas specific SNP testing accurately defines a haplogroup. The current approved haplotree is at ISOGG; and current haplogroup designations against specific SNPs are at Y-DNA SNP Source

  • Cokayne, GE: The Complete Peerage, 1st edn, 8 vols, Volume 4, page 138. The best information Cokayne had, relying on the opinions of "authorities", was that Sir James was alive in 1451. On this basis, he assigns the creation of the Parliamentary title in 1445 to this James and not to his son.

1st: Concerning the father of James Hamilton (1st Lord) 5th Baron of Cadzow. I disagree with the following article: http://www.personal.psu.edu/users/g/a/gah4/HamDNA/Results.html#eigSection: 8. Which Groups Are Derived from Well Established and Documented British Lines?Just noting "close relative" and "more recent DNA results" and "conclusive" statements. I will have to research their "findings" . Seems speculative, although not impossible. Not having the DNA of the actual people referred in the article, although the article states "most recent" information, makes their "findings" quite inconclusive. (Continued in 2nd comment)

2nd: I am wondering why James had an uncle named John (Hamilton of Butterknock or 1st of Bardowie, born 1375) and his father was also named John (Hamilton 4th of Cadzow, born 1370, first son). Also why the brother of James (Walter Hamilton of Raploch) shared DNA, supposedly, with this "uncle" of James. Rarely in the Hamilton line will you find 2 full (not half) "brothers" with the same given name. I will continue searching for an answer to this and many other questions that the "well established" and so-called "documented" informationists have brought to our attention. (Continued in 3rd part)

3rd: And I do understand that the author of the article, Gordon Hamilton took the DNA sample from the cheek of his grandfather John Prouty PEPPER to come to the conclusion that his Y-DNA may have showed him that he was a Scottish descendant of "John Hamilton". Are there any family trees available for him or others involved?
