GUTHRIES of AYRSHIRE, SCT / (PA, MD, & VA) USA / CAN / NZ

🧬 Guthrie Family Group 3A: An Overview
Guthrie Family Group 3A (GFG3A) represents a significant cluster of the Guthrie clan with deep roots in Scotland and expansive migrations to the Americas and New Zealand. Recent DNA advancements, specifically the Big Y-700 test, have provided a high-definition map of how these branches diverged from a common ancestor in the 1400s-1600s.
🌳 The Genetic Landscape (Big Y-700 Analysis)
The attached Block Tree reveals the precise SNP (Single Nucleotide Polymorphism) markers that define this group:

- R-BY12113 (~1400 CE): The foundational marker for this cluster. The red icon represents the Most Recent Common Ancestor for both American and New Zealand Branches.
- R-BY12121 (~1600 CE): A major split point. This lineage eventually leads to the American “Francis Guthrie Sr” descendants and the “John Guthrie/Mary Fuller” line.
- R-FTC5164: A distinct sub-branch that includes the New Zealand Guthrie line (William b.1763 SCT) and, interestingly, a genetic match to the William Gray lineage.


🔍 Detailed Branch Breakdown
Branch A: Descendants of Francis Guthrie, Sr.
This branch constitutes the primary American lineage of GFG3A. It is important to note that this branch has undergone some changes compared to the original published theories presented in ‘American Guthrie and Allied Families,’ by author Lawrence R. Guthrie. Collaborative research by Guthrie Genealogy members has provided new evidence as to the identities of Francies Guthrie Sr.’s sons. Genetic testing of descendants from all three sons has confirmed their shared Guthrie origin.
Guthrie Genealogy blog articles discuss the details:
GFG3 Theories: Part 1
GFG3 Theories: Part 2
The Forgotten Sons
- Sub-Branch 3A-1: Robert Guthrie & Esther Giles
- A well-documented line often found in early Virginia and Pennsylvania records.
- Children: Ann Guthrie (m. FNU King); John Guthrie (m.Mary Fuller), Phebe Guthrie (m. John Gadberry), Mary Guthrie (m1. Ephraim Skiles Jr; m2. John Scott), James Guthrie (unmarried?, died before 1788), Sarah Guthrie (m1. Isaac Davis, m2. John Van Lear Sr), Richard Guthrie (m. Elizabeth Esther McIntosh), Robert Guthrie (unmarried; died c1794).
- Sub-Branch 3A-2: Francis Guthrie Jr. & Susannah (MNU)
- Francis Guthrie Jr’s identity was overlooked in early PA records merging him with his father, but he was indeed a separate individual.
- Research continues to identify Susannah’s maiden name to unlock further autosomal connections.
- Children: Alexander Guthrie (m. Jean McFerran), Francis Guthrie (speculative, marital status unknown), Nancy Guthrie (m. Thomas Cribbins), James W Guthrie (m. Isabella Carmichael), William Guthrie (m. Hannah Smiley).
- Sub-Branch 3A-3: John Guthrie & Unidentified Spouse
- John Guthrie was another ‘Forgotten Son’ of Francis Guthrie Sr. His spouse remains unidentified.
- Children: James Guthrie (m. Elizabeth Casdorph), Susan Guthrie (m. Henry Casdorph), Alexander Guthrie (m. Eleanor Amis), Robert Guthrie (m. Frances Fowler), Anne Guthrie (m. Elijah Fowler), Mary ‘Polly’ Guthrie (m. James Kitchen).
Branch B: The Scottish & New Zealand Line
This branch is defined by William Guthrie (b. 1763, SCT). His descendants migrated to New Zealand, maintaining a distinct genetic signature (R-FTC5164) shared with the Gray lineage.
- New Discovery: Autosomal DNA research has recently linked this branch to George Guthrie (1728-1802) and Margaret Bowie.
- Elite Connections: This discovery links Branch B to the family of Christina Guthrie of Mount, Lady Oranmore, elevating the genealogical profile of the group.
- Deep Ancestry: The lineage is theorized to trace back to George Guthrie (1660-1712) and Isobald Hewie via their son John Guthrie (1690-1743) and Janet Howie.
🧩 The “William Gray” Mystery
One of the most intriguing results of the Big Y-700 test is the inclusion of a descendant of William Gray within the Guthrie GFG3A block.
- The Connection: The Gray participant shares the R-FTC5164 marker with William Guthrie (b. 1763).
- The Implication: This suggests that either a Gray ancestor was biologically a Guthrie, or vice-versa, occurring likely in the early-to-mid 1700s in Scotland. It highlights the power of Y-DNA to reveal family secrets that paper records cannot.
🧪Speculative Relationships: The Pitforthie Mystery
A significant point of research for GFG3A is the ancestral connection to the Guthries of Pitforthie. While tradition and certain autosomal links suggest this lineage, the genetic data presents a fascinating “two-claimant” riddle involving both GFG3A and another distinct group, GFG2A.
The Key Figure: Rev. John Guthrie
Rev. John Guthrie, the Minister of Tarbolton, was the youngest son of James Guthrie and Janet Lyon of Pitforthie. His life was defined by the religious and political upheaval of the Covenanter period.
- Residence: Tarbolton Parish, South Ayrshire—a rural area of 18.9 sq. miles famous for its later association with Robert Burns and the “Bachelors’ Club.”
- The Conflict: Charged with treason during the Covenanter era, his death sentence was commuted. However, records of his later life and death are plagued by conflicting dates and details.
One Progenitor, Two Genetic Identities?
The core mystery lies in whether Rev. John Guthrie left descendants, and if so, which genetic group they belong to. There are currently two competing theories:

The Tarbolton Connection
If GFG3A is indeed the true biological descendant of the Pitforthie line through Rev. John, it places the family at the heart of South Ayrshire’s history. The proximity to the towns of Mauchline and Prestwick suggests a lineage that was well-integrated into the Scottish Lowlands before the migrations of the 1700s.
Research Note: The conflicting information regarding Rev. John’s death is the “smoking gun.” If he died shortly after his sentence in Scotland without issue, then neither group may be his direct descendants. If he lived, the genetic “fork in the road” between the Irish GFG2A and the Scottish GFG3A remains the most compelling mystery in Guthrie genealogy.
🏁 Summary for Researchers: The Road to Pitforthie
The GFG3A study has evolved from a simple search for American ancestors into a high-stakes investigation of Scottish ecclesiastical history. The data now positions this group at a historical crossroads, directly challenging the traditional narrative of another genetic group (GFG2A).
The Pitforthie Conflict
We are currently faced with a “Two John Guthries” problem. Both GFG3A and GFG2A claim descent from the Guthries of Pitforthie via the Rev. John Guthrie of Tarbolton. However, DNA proves these two groups are not biologically related within a genealogical timeframe.
Resolution Roadmap
To resolve whether GFG3A is the true biological heir to the Pitforthie line, research must focus on three critical areas:
- The “Ayrshire Stay”: We must verify if the Rev. John Guthrie’s commuted sentence allowed him to remain in the Tarbolton/Ayrshire area. If GFG3A (specifically the 3B branch) can solidify the link between George Guthrie (1660) and the Reverend, it confirms GFG3A as the Pitforthie line.
- The “Irish Flight”: Conversely, if evidence surfaces that Rev. John definitely fled to Ireland and married Jane Stuart, the GFG2A claim gains weight, suggesting GFG3A might descend from a different Guthrie branch entirely.
- The Gray Factor: The presence of the William Gray match in GFG3A is a wild card. It suggests a potential surname change or NPE in the early 1700s near Ayrshire. Determining when the Gray/Guthrie split occurred will help date the Guthrie presence in that region.
Strategic Objectives
- Big Y-700 Expansion: We need more GFG3A participants from the Branch 3A-3 (John Guthrie) line to see if their SNP markers pre-date the 1600s split, providing a clearer “clock” for the Pitforthie connection.
- Targeted Autosomal Testing: Focus on descendants of the Lady Oranmore line. If their DNA consistently triangulates with GFG3A members and not GFG2A members, the “Pitforthie Resolution” tips strongly in favor of GFG3A.
- Archivial Deep-Dive: A search for Tarbolton manse records or Covenanter-era pardons may provide the definitive “paper trail” regarding Rev. John’s movements post-sentencing.
The Bottom Line: While the paper trail is currently tangled, the DNA is clear—only one of these groups can be the biological Pitforthie line. GFG3A’s recent connection to the Guthrie of Mount estate makes it a formidable candidate for the true lineage.

I just found the death date for my 3 gtgrandma, Jane E Shelton [Guthrie]. She married Robertson Shelton in Giles Co.VA in 1816. One sister’ married Phillip Ballard before 22 Nov. 1811 the date of birth of their son Robertson Shelton Ballard in Logan Co. VA On 01 Aug. 1819 in Logan Co. Jane and Robertson had their first son Sylvester. It states that Phillip’ mother was a Robertson also. Seeing that these families all moved to Indiana, Henry, Rush and Blackford Co’s we find Robertson Shelton, Gordon Ballard and Robertson Ballard witnessing Wills.Phillips wife was Eleanor Guthrie with children, Cyrus Austin, Mary Jane, Thomas Griffith, Chrales Henry and William Rogers.I can comfortably assume that Robertson Shelton Ballard was named in honor of Phillips brother-in-law. Jane E. Guthrie was born in Maryland the daughter William with her sister Martha ‘Patsy’ marring Martin Moody in 1808. Martha was born in Bedford Co VA in 1886. My quest here is find more about William. Craig Holland
Jane Guthrie & Robertson Shelton are new names for me. There are no current members of the Guthrie DNA Project listing them as ancestors, nor do I show them listed in my extensive Guthrie Research tree. Which basically means now I need to learn more. Random trees show Jane as the daughter of William Guthrie and Mary Warren Musgrove. This couple is credited with several sons and a daughter named Martha Jane, but I show her listed as being married to a Jesse Stansell rather than a Martin Moody. Martha Jane was not born until 1820, and William & Mary’s other children were estimated to be born sometime after 1809. So my main question is whether Jane is attached to the right parents in these trees. Is there documentation proving Jane and Martha’s father was named William? Have you taken an Autosomal DNA test? It might point toward a particular Guthrie Family Group. The family of William Guthrey & Mary Warren Musgrove remains ungrouped as we do not have descendants from that line participating in the project at this time.
I found a book at the Internet Archive site with information on William Guthrie (who is indeed not the man who married Mary Musgrove). There is currently no DNA data associated with this family.

Dear Ann: Thanks for your reply. This past Friday I received a query from a party in Giles Co. Her lore created Guthrie family tree was full of hints and I will forward to her the Robert Guthrie and Esther Giles tree which will make her kin very happy. I have somewhere in my files a mention of William Guthrie being in Frederick Co. Maryland. But I do have a page from 1815 Tax Lists for Giles Co. This lists the family of William Guthrie in 1810 with Jane, Mary, Martha and Eleanor with their respected husbands except Jane who marries in 1816. No I have not taken that DNA test, but I should. Please inform me and eager to hear if anything you find in your recent William Guthrie source.
I don’t see a TN connection for your William Guthrie and children. They appear to have moved to Indiana after his death in Virginia. I don’t have a copy of a 1815 Giles County TN Tax List. The 1812 Tax List has only Robert Guthrie on it. (TNGenWeb). Unfortunately, the Giles County Courthouse burned in 1813 taking its marriage and probate records with it. The county had been formed in 1809 from Maury County, TN, so that could potentially be a place to find clues if they did have ties to Giles County.
I think the discussion is about the William Guthrie family of Logan WV (formerly Giles VA), not TN. As far as I know, this William had no sons and was only in Logan WV for a relatively brief time. I grew up in Giles VA. The query received by Mr. Holland is likely from one of my close relatives, but I don’t know from whom it would have been.
