The 1792 subscribers to Janet Little’s poems include William Guthrie at Harperland. A separate “Mr. J. Guthrie” at Dollars should not be assigned to this family without additional evidence.

The legacy research cites the 1797–1798 farm-horse tax rolls, including volume 7, image 210. It also preserves a volume 1 reference whose original hyperlink is malformed. The Ayrshire land-tax entry names Alexander Fairlie as the Harperland landowner: it is contextual evidence for the property, not proof that William owned it.

The Star of 14 April 1801 reports a ploughing award to John Smith, servant to William Guthrie of Harperland. The award belongs to Smith. The Agricultural Magazine in 1809 reports a first premium for William’s cattle breeding. William Aiton’s General View of the Agriculture of the County of Ayr (1811) discusses William’s preference for greater freedom in crop rotation on the Fairlie estate of Sir William Cunningham.

The “Centenary History of Troon and District, 1805–1895” extract associated with Dykes, the Kilmarnock Standard and Ayr Library was supplied through Sharyn Guthrie’s research and discussed in the 2019 theories article. Retain it as attributed historical context. Its reported 1847 death for William, and an impossible parentage involving Alexander born in 1783, are not adopted. The related paper titled “Answers to Queries Regarding Leveling and Straightening of Lands” remains a useful agricultural research lead.

The original census page is 590/3/7, headed Troon, with the household at Loans. It lists Wm Guthrie, 70, farmer, and James Guthrie, 35, both marked as born in the county. The 1841 form does not state relationships.

William’s accepted identification with the child baptized in 1763 is retained, while the age discrepancy is made explicit. He would have been about 78; ordinary five-year age rounding does not explain an entry of 70. James’s recorded age also differs from his 1797 baptism. The census must not be used to create an exact 1771 birth date or to replace the baptism.

The project provisionally accepts three earlier generations on the basis of triangulated autosomal DNA evidence considered with the family’s documentary reconstruction. This extension remains explicitly provisional. A collateral paternal-line Y-DNA/Big Y comparison would provide a different and valuable test of the proposed connections.

The working sequence is George Guthrie & Isobald Hewie → John Guthrie & Janet Howie → George Guthrie & Margaret Bowie → William Guthrie. Shared DNA supports investigation of ancestry; it does not by itself identify every parent in the sequence.

The Ayrshire OPR search using the prefixes “Geo” and “Gut” for 1634–1639 returned no matching Ayrshire baptism. The single Scotland-wide result was George Guthree, dated 31 January 1634 in Edinburgh, son of Alexander Guthree and Jeane Gilchryst (685/1, 40/192). No connection to this Ayrshire family has been established. That search result is not proof that no baptism occurred, and the Edinburgh child should not be substituted.

The earliest George cannot be made a son of the Rev. John Guthrie of Tarbolton, born in 1633, on the adopted chronology. A descent from the Pitforthie family, and a named common ancestor shared with the American Branch A, remain unproved.

The memorial account appears in the 1913 Journal of the Association for the Preservation of the Memorials of the Dead, Ireland, vol. IX, pp. 407–408. Lord Oranmore and Browne supplied the description and reported moving the marker from Scotland to Castle MacGarrett in 1907. The journal is the available witness to the inscription, not a newly inspected original stone.

The family account reports George Guthrie’s death on 21 March 1802 and Margaret Bowie’s on 4 September 1814, with a memorial erected in 1832. Their son John, baptized in 1761, is reconstructed as the husband of Helen Hutchison, married 30 July 1782 and died 23 January 1827. A son Alexander was baptized at Riccarton on 30 April 1783. These collateral records are important to the accepted working pedigree and should be correlated through original parish and estate evidence.

The supplied earlier-generation packet preserves the John Guthrie baptism and memorial transcriptions alongside the sasine. They are retained at their actual evidentiary level: the 1739/1740 land-security document directly locates John at Sidehead but does not independently prove each parent–child step.

The Craigie marriage register, 584/10/268, records John Guthrie “here” and Janet Howie of Riccarton entering their names for proclamation on 15 January 1725. This is evidence of the proclamation process; it does not independently establish the wedding date.

The photographed sasine in RS14/10 identifies “John Guthrie in Sydehead of Cairnhill.” The instrument is dated 6 November 1739 and was registered at Ayr on 5 January 1740. It concerns a heritable bond securing 2,200 merks Scots, with annualrent of 110 merks, against property described as Mossyde and associated ground in Craigie parish.

The named son-and-heir relationship is between Alexander Thomson and his deceased father, also Alexander Thomson. It is not a Guthrie parentage statement. The document does not name John’s wife, parents or children, and it does not establish that John purchased Cairnhill outright.

The records below distinguish original entries, attributed transcriptions and later accounts. Linked repositories may require an account or subscription. A link is a locator, not a claim that every underlying image has been independently examined.
