Guthrie Family Groups
What are Guthrie Family Groups?
- Guthries that descend from a common paternal ancestor.
- Determination of family grouping is confirmed through YDNA testing of Guthrie men (direct paternal line testing).
- Lineages with documented association to a YDNA tested line are then inferred to belong to that group unless new genetic evidence proves otherwise.
- The groups are not biologically related to one another on their direct Guthrie lines.
Y-DNA Testing is the Key.
Direct paternal line testing using YDNA from Guthrie men is the best source for confirming a match to a specific group. Autosomal DNA testing can also provide clues as to group origin, however results might be inconclusive. It is best to test the older generation of the family. A male Guthrie with a single YDNA test may provide all the data needed to identify group origins, while it may take 50+ autosomal tests to find enough matching components to officially triangulate results.
Genetic Mismatches Happen.
Exceptions to the grouping process occur when the paper trail appears to be rock-solid, but YDNA does not match the expected group. These mismatches happen through causal events such as adoption, false paternity, and feudal laws can affect expectations. These genetic diversions can lead to a whole new group being formed if there are many people affected, or to a subgroup of the original.
Ungrouped Families Need Y-DNA.
Untested lineages with a documented paper trail are inferred to belong to their associated group unless a YDNA test proves otherwise. Note that oral traditions about family origins and mistaken identities have led to errors in documentation. DNA testing can correct those misconceptions.
Established Guthrie Family Groups:
The number of Guthrie Family Groups may change over time as new groups are created. There are currently 15 genetically distinct groups. They are not genetically related to one another and therefore do not share any Guthrie ancestry.
GFG1A descendants include the Guthries of Craigie, the Guthries of Middlesex County, Virginia, and the Guthries of Worcester County, Maryland. Likely historically descended from the Guthries of Guthrie, builders of Guthrie Castle, if the genetic line holds.
GFG2A is the largest of all Guthrie Family Groups consisting of 13 major branches with ties to Scotland, Northern Ireland, Canada and the majority of the American Colonies. Individual branches may share more recent common ancestry than the progenitor of the overall group. The origin story for GFG2A indicates they descend from the Guthries of Pitforthie.
GFG3A includes 2 lineages that trace directly back to Scotland, one found in Angus and the other in Ayrshire. The earliest American branches of this group are found in Pennsylvania, Virginia and Maryland moving on to Ohio and Indiana.
GFG4 lineages seem to point back to a single couple in colonial Virginia, Thomas Guthery & Sarah Oakes. While it is possible that earlier generations of this family remain undiscovered, there is currently no documentation or genetic evidence to support it. This group is the possible result of a Causal Event dating back to the late 1600s to early 1700s.
GFG5’s earliest lineage traces back to William Guthrie & Eleanor Harris Abbott, frequently (and erroneously) linked to another group. For a time, it was considered that William Guthrie might be the result of a Causal Event. New evidence suggests that might not be the case. Instead, they may have a connection to the Guthries of Carteret County, NC. More genetic testing of lineages from that area is required for confirmation.
GFG6 is likely a very old Guthrie family. This group has the most genetic diversity within its own matches suggesting that the most recent common ancestor is very distant. Related lineages are found in Scotland, Northern Ireland, Canada & the USA: DE, NY, PA, VA.
GFG7 is one of our smaller groups consisting of one American and one Australian line. The most recent common ancestor likely lived in Scotland, possibly in Ayrshire.
GFG8 is likely of Irish origin resulting from a Causal Event with a man of the Vaughan or Roddy/Ruddy surname. The earliest Guthrie lineage for this group is that of Thomas Guthrie & Mary Cason of Halifax County, Virginia, indicating the historical Guthrie line for this family probably originated in Ireland.
GFG9 consists of only one family lineage from the Orkney Islands in Scotland. Common surname matches are to Green and Padgett, however there are only 2 participants in the group at this time. More participation is needed to determine if the results affect only part of the line or all of it.
GFG10 results from a known adoption into the Guthrie family of Bull’s Gap in Eastern Tennessee. Andrew S Guthrie & Isabella Rader’s descendants belong to this group. Surname matches at the Y67 level are Cameron and Perry.
GFG11 includes descendants of George Guthery and Mary Young, and other lineages likely to branch from their direct line. Men from this group match the Ballew/Ballou surname indicating a Causal Event probably in the early to mid 1700s.
GFG12 is another small group of two lineages. One originated in Scotland immigrating to Indiana, while the other came to Ohio by way of Ireland. Chances are that the common ancestor is back in Scotland. The majority of surname matches for these two men is Benbow making this a likely Causal Event from the early to mid 1700s.
GFG13 currently has three connections. One from NC/SC/TN, one from SC/GA/AL, and the last from IRE/NY. The most common surname match is Gillespie, so this could be the result of another Causal Event, probably from the early 1700s.
GFG14 has three Guthrie participants whose ancestors lived in New York. These men match people of the Joyce surname indicating another Causal Event, probably dating back to the early to mid 1700s.
GFG15 is associated with the Guthrie families from Adams County and Brown County, Ohio. Their common ancestor is likely to be Joseph Guthrie of Adams County, Ohio, who also lived in Pennsylvania and Virginia.
GFG16: Lineages from Australia and Canada trace their Robert Guthrie 1776 Dunbartonshire, Scotland – 1827 Lanarkshire, Scotland & Janet Andrew.
More details on each Guthrie Family Group and their associated lineages can be found on the dropdown menu. If you don’t find your ancestors listed under one of the established groups, it could be that we don’t have the documented evidence or a Y-DNA match to prove ties to a specific group.
