GFG14

Unraveling the Mysteries of Guthrie Family Group 14 (GFG14)
Greetings, Guthrie descendants and researchers! GFG14 uncovers the story of George Nelson Guthrie and his kin through history, migration, and DNA surprises. Join us in piecing together this Revolutionary-era puzzle.
Background and History
- Progenitor: George Nelson Guthrie (c. 1750s–early 1800s) had four Patriot brothers who fought in the American Revolution.
- Role and Migration: Protected family by moving west from New York, possibly through Pennsylvania to Ohio, amid wartime dangers.
- Origin Theory: Likely Irish or colonial roots; candidate: George Guthrie (c. 1750 IRE – bef. Apr 1810) in Washington Co., NY.
- Potential Brothers: Samuel Guthrie, John Guthrie, others?
- Context: Era of displacement, name variations, and incomplete records; implications include family reinvention and westward expansion.
- Nuances/Edge Cases: Blended families, post-war economic shifts; some lines split by loyalties.
GFG14 Branches and Progenitors
- Branch A: Descendants of George Nelson Guthrie & Unknown (MNU)
- Branch B: Descendants of William Guthrie 1803NY-1853NY & Susan Wright – unclear if descent is via George or a brother.
GUTHRIE-UNKNOWN
There is no documentation on the identity of George Nelson Guthrie’s brothers or parents. This was a family of “pioneers, farmers, and distillers.” The route taken was reportedly from NY to NJ into PA and then OH.
GUTHRIE-WRIGHT
William Guthrie was born in NY on 18 Jul 1803. So, his parents were still in NY by the time George Nelson Guthrie had taken his family away from the area. William remained in NY his entire life, and married in 1831 to Susan Wright in Salem, Washington County, NY. Her family was from Hebron, Washington, NY. William was a cooper by trade.
- Other Potential: Sibling lines unconfirmed; more testers needed.
- Patterns: Intermarriages, migrations; diverse pursuits (farming to industry).
- Y-DNA Representation: 5 testers (3x Y-37, 1x Y-67, 1x Big Y-700); suggests shared profile across family.


Mistaken Identity Issues: Navigating the Genealogical Pitfalls
One of the most persistent challenges in GFG14 research is mistaken identity, where well-intentioned family trees conflate distinct individuals. A prime example is the confusion between our George Nelson Guthrie and George Guthrie, son of Robert Guthrie and Bridget Dougherty from GFG2A – Branch E. These were unequivocally two different men:
- This George (GFG14): New York-based, Revolutionary patriot brothers, westward migrant; no confirmed ties to Dougherty.
- The Other George (GFG2A-E): Likely Pennsylvania/Irish roots, different timeline and family associations; DNA mismatches confirm separation.
This mix-up stems from similar names, overlapping eras, and incomplete records. Family trees on platforms like Ancestry or FamilySearch often merge them due to user errors, propagating inaccuracies. Nuances include phonetic surname variations and recycled first names in large families. Implications? Such errors can derail inheritance claims, historical reenactments, or even DNA kit interpretations. Edge cases involve “brick walls” where records were destroyed (e.g., courthouse fires) or pseudonyms used during wartime.
To avoid pitfalls: Cross-reference with primary sources like Revolutionary War pension files, land deeds, and DNA. The Guthrie DNA Project actively debunks these myths, ensuring accurate lineages.

Analysis of Big Y and Joyce Matching: The DNA Revelation
The genetic backbone of GFG14 lies in Y-DNA, which traces patrilineal descent. All five tested Guthrie men match closely, but the real bombshell? Their profiles align not with traditional Guthries but with men bearing the Joyce/Joice surname. This suggests George Nelson Guthrie’s incorporation into the Guthrie family via a Non-Paternity Event (NPE)—possibly adoption, a step-child scenario, illegitimacy, or a deliberate name change. Research to pinpoint George’s biological origins remains inconclusive, but the DNA points to a Joyce paternal line.
The standout is the Big Y-700 test from one participant, enabling a detailed “Match Time Tree” analysis (as visualized in the provided diagram). This tree, spanning 1300 CE to modern times, illustrates haplogroup evolution:
- Root Haplogroup: Starts with R-Y7729 around 1300 CE, a broad European marker.
- Branching Points: Progresses through R-FT71988 (1400s), R-F239478 (1500s), and finer subclades like R-Y12101 (1600s), R-FTB42619 (1700s), R-M105215 (1800s), R-Y43252 (1800s), R-FTA92314 (1800s), R-FTD34424 (1800s), and R-FTB3897 (1800s).
- Modern Matches: The tree fans out to 20+ individuals, overwhelmingly Joyces (e.g., Thomas Joyce 1609–1665, Vincent Dwayne Joyce, Mark Douglas Joyce). A few Joss/Joice variants appear, with timelines clustering in 1700–1900 CE. The Guthrie tester branches near 1800 CE, suggesting a common ancestor with Joyces around the Revolutionary period.
This implies the entire GFG14 family—possibly including George’s brothers—shares this Joyce-derived Y-DNA. For Branch B (William Guthrie’s line), the match strengthens the case for a unified profile, though descent specifics need more testers.
Implications? This NPE challenges romanticized family lore but enriches it—perhaps George was adopted post-Revolution or changed names for protection. Nuances: Y-DNA only traces one line; mtDNA or autosomal could reveal more. Edge cases include cultural name shifts (e.g., anglicization from Joice to Guthrie). The Guthrie DNA Project views this as a breakthrough, urging Joyce descendants to test for cross-matches. Broader context: Such findings highlight genealogy’s evolution from paper trails to genomics, reshaping identities.
In closing, GFG14 is more than a family group—it’s a testament to adaptability and discovery. Join the Guthrie DNA Project, share your stories, and let’s expand this tree together. Questions or contributions? Dive in!
