Active interest in identifying the origins of my Seymour ancestors primarily through DNA analysis. Enjoy the puzzle of finding ones cousins.

In addition to I can be found on, 23&me, FTDA, GedMatch (& Genesis),, yFull and ySearch.

For those who are willing to make their DNA data public I would recommend GedMatch (registration), Genesis (register with GedMatch) ,, yFull, and ySearch. For those who have had their complete mtDNA tested please consider GenBank.

Paternal DNA tests of STR and SNP appear to define a group of individuals which share a close genetic relationship between each other. The paternal surnames of this group include Arnold, Bennett, Coat, Follis/Fallis, Locke, Robinson, Seymour, Smith and Ware. Roughly speaking we share a common ancestry within the last 1300 years or so. About 800 or 900 years ago this group split into two subgroups, the Arnold, Follis/Fallis, Robinson (& Hoppins), Seymour, Smith, and Ware subgroup and the Bennett, Coat, and Locke subgroup.

The DNA signature for these two subggroups includes both SNP and STR results. FTDNA currently defines two subclades for the two subgroups. The SNP, FGC29330/BY3299, defines the Bennett/Coat/Locke subgroup and the BY3298 SNP for Arnold, Follis, et al group. Note 1 provides details of the relevant STRs and or subclades as currently defined by FTDNA and yFull. The largest genetic distance (GD) between individuals I consider part of either group is at least 26 (FTDNA111) (or a GD ratio of 0.234 (26 / 111)). I would recommend that most individuals who may fit either surname group should consider STR testing to the 67 or 111 level. Additional BigY testing (FTDNA) or similar would be extremely useful to define the subclade structure as well as providing better time estimates of subclade formation. BigY results can be analyzed by ($50) for up to 500 DYS.

Anyone who thinks they may be part of either surname group should consider joining the BCProj.

DNA Tested
Denny Seymour's DNA has been tested for genealogical purposes. It may be possible to confirm family relationships by comparing test results with Denny or other carriers of his ancestors' Y-chromosome or mitochondrial DNA. Y-chromosome DNA test-takers in his direct paternal line on WikiTree:
  • Denny Seymour: Family Tree DNA Y-DNA Test 111 markers, haplogroup R-BY3298, FTDNA kit #108347 + Y-Chromosome Test 419 markers, haplogroup R-Y20344
  • Matt Seymour Find Relationship : Family Tree DNA Y-DNA Test 111 markers, haplogroup R-M269, FTDNA kit #656850
Mitochondrial DNA test-takers in the direct maternal line:
  • Denny Seymour: Family Tree DNA mtDNA Test Full Sequence, haplogroup J2b1b, FTDNA kit #108347
It is likely that these autosomal DNA test-takers will share DNA with Denny:
  • Denny Seymour: 23andMe, GEDmatch M122189 [compare] + AncestryDNA, GEDmatch A741529 [compare], Ancestry member dseymour + Family Tree DNA Family Finder, GEDmatch T819182 [compare], FTDNA kit #108347

Hey Denny,

Now that you have had a little time to try WikiTree, there are a few features you may find useful.

Ideas on what to include in a profile can be found in Styles and Standards.

If you need to describe an event, heirloom or a location relevant to your research, try Free Space Profiles.

If you run into unresponsive profile managers. We have a process for resolving these unfortunate situations.

A project of note is the Global Family Reunion check it out at Global Family Reunion.

You are now a member of the WikiTree Community Denny.

We are building one Collaborative Tree which means one profile per person. It is important to check for duplicates as you add any Profiles to WikiTree - the software automatically helps with this.

If you need any help, visit the G2G forum. You might want to check out the introductory WikiTree video that a member created.

Our Mentor Team are a friendly bunch of volunteers who will be glad to help you.

You will find many ways to participate in WikiTree as you explore the community. Thanks for offering to help build our shared tree :)

Enjoy the puzzle of connecting people by traditional genealogy as well as DNA data. Will try to help where I can and hopefully will provide information others may find of value. We all collectively owe a large debt to those we have followed and to those today that are making our task easier.
