What are Guthrie Family Groups?

1. Guthrie individuals / families / lineages all descending from a common paternal ancestor.
2. The groups are genetically unique and not biologically related to any other group on their Guthrie line.
3. If you have only 1 Guthrie line in your tree, you can only belong to 1 Guthrie Family Group.
4. Determination of family grouping is confirmed through YDNA testing of Guthrie men (direct paternal line testing).
5. Lineages with documented association to any YDNA tested line are inferred to belong to that group unless new genetic evidence proves otherwise.

If you’re not sure where your family line belongs, just ask under the ‘Questions’ section.

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. The earliest genetically proven ancestors are James Guthrie 1669-1710 (merchant) and Christian Scott.5qw1

GFG2A is the largest of all Guthrie Family Groups consisting of many major branches with ties to Scotland, Northern Ireland, Canada and the majority of the American Colonies. Individual branches may also share more recent common ancestry than the progenitor of the overall group. The origin story for GFG2A indicates some branches may 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 oldest lineage traces back to William Guthrie & Eleanor Harris Abbott. This couple is not genetically related to the Guthries of Middlesex, VA (see GFG1A). Early publications suggest that William is a son of Edward Guthrie of King & Queen County, VA. Genetic evidence is pending. Also speculated are GFG5 ties to the Guthries of Carteret County, NC and Thickety Creek, Spartanburg County, SC. YDNA is needed for confirmation of a group match.

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. It appears to result from a Non-Paternal Event or adoption. 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 YDNA 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.

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 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.

GFG17: Lineages from Menmuir & Cortachy in Angus, Scotland theorized to descend from David Guthrie and Janet Stewart in Cookston and Balbirnie Mill.

GFG18: Lineages descending from William and Mary (MNU) Guthrie of Mondooey, County Donegal, Ireland.

GFG19: Lineages from Aberdeenshire and Inverness-shire, Scotland.

HOW DO YOU FIND YOUR GUTHRIE FAMILY GROUP?

Use the Search Tool. Enter the names of your earliest known ancestors.

Check my Guthrie Research Tree on Ancestry.com. Due to the large size of the tree, it’s easier if you search for the spouse rather than the Guthrie. Once you find your ancestor in the tree, use the tool to View the Tree and you’ll be able to see if your family line is already attached to an established Guthrie Family Group or remains in an Ungrouped Family Status.

If you’re still not sure where your family fits, use the ‘Questions’ or ‘Contact’ section to get help.

ESTABLISHED GROUPS:
The Guthrie Research Tree is not your only place to explore family connections, related lineages, and find documentation.

Details for each Guthrie Family Group and associated lineages can be found on the dropdown menu.

UNGROUPED FAMILY STATUS:
Groups are formed when we have 2 or more Guthrie men with matching Y-DNA (direct paternal line) tests. Families that do not have a Y-DNA participant in the project, or cannot infer their relationship to an established group through original documentation, are placed in an Ungrouped Family Status until such evidence comes along.

Some of the Ungrouped Families are listed on the website. See the Guthrie Family Groups dropdown menu to access those pages. Participating Autosomal DNA Kits are listed there. The most important thing descendants in an Ungrouped Family Status can do to connect their family to an established group is to seek out their closest male Guthrie relative for a Y-DNA test. These tests may be fully sponsored by you or potentially by the project. Your can cost-share the test with your relative or a group of relatives. Ask how if this is something you’re interested in.
