This is a One Name Study to collect together in one place everything about the Duncan surname and its variants. The hope is that other researchers like you will join the study to help make it a valuable reference point for people studying lines that cross or intersect. Please contact the project leader, add categories to your profiles, add your questions to the bulletin board or G2G (tagged Duncan), add details of your name research, etc.

The following template will be used to indicated profiles under current review by the Duncan Name Study.

This profile is part of the Duncan Name Study.
This profile is under active study, please coordinate any changes with Duncan Name Study manager

This DNA Duncan Project is designed to get the descendants of the Duncan (and all the spelling variants) who immigrated to the United States to be confirmed via DNA triangulation, eventually connecting us to our cousins that live across the pond. This study seeks to use ALL of the available tools to accomplish this. You do not have to have a DNA test to participate, but it does help.

The project is to firm up all "unknown" confidence levels of these Duncan relatives to

  • 1: Confident or ideally to
  • 2: DNA Confirmed and turn the DNA ticker on.

The basis of this study is to compare DNA kits to each other to determine where we connect with each other. To participate is easy, upload your DNA to Gedmatch and let me know what your Gedmatch kit # is. This blog explains on how to do that:


Will you join me? Please post a comment here on this page, in G2G using the Duncan name tag or send me a private message.

At the very least we seek to firmly show we have all the right people in place (family units) all confirmed via available written records and hopefully DNA DUNCAN confirmed.

Task List

Here are some of the tasks that I think need to be done. I'll be working on them, and could use your help

  • Find Duncan descendants that have taken a DNA test. In Progress
  • Invitation of DNA test takers to consent to upload raw data to GEDMatch for triangulation (and assist through the process).
    • Invite Duncan descendants to participate in our Duncan DNA confirmation project and WikiTree.
  • Use clues provided by DNA to research for documentation.
  • Add Duncans to WikiTree and place unconnected Duncan profiles in their family units.
  • Improve unsourced and orphaned profiles.
  • Use DNA triangulation to figure out and verify the MRCA and mark them DNA confirmed.
  • Repeat the process to verify the next ancestor.
    • The use of DNA Painter in this study is new. I will update progress on this page when I get it completely set up.

My hope is to help Duncan descendants solve their Duncan brick walls, and figure out what family groups our Duncan ancestors belonged to. Every one of our Duncan broken lines had parents - we just cant find them! According to Forebears over 177,000 people carry the Duncan surname in the United States and over 12,000 Duncan profiles in WikiTree. Alot of the records are muddied and uncertain in the early years of the US. Not all of us have taken DNA tests, but some have. Of those that have taken a DNA test, an even a smaller group is really interested in doing the genealogy research to find our family ancestors. If you are one of the ones that have an unbroken Duncan line, I envy you. I am one that has a broken Duncan line and have exhausted traditional genealogy methods. We aught to be able to get together to solve this!

Using DNA in genealogy research is fairly new, and more and more are getting an autosomal DNA test. Particular methods have been developed to help adoptees, and we can use those methods to help us. Because WikiTree uses collaboration, I find that WikiTree is particularly suited to use those methods.

If you are a Duncan descendant, I want to hear from you.

DNA Research

I am am this time taking the time to research for more tools. DNA Painter has promise to help organize DNA matches. I am in the process of revamping the DNA portion of the Duncan Name Study and will be changing how the information is collected and organized. Please bear with me. I will have this updated soon!

Come Join the team!

I am interested in helping this project. I have unbroken line in Scotland back to 1680. My name is Louise Duncan

I am Jeffery Duncan and as far as my dad and my grandfather has told me we have always held the last name Duncan my grandfather said his grandfather he remembers was a Duncan my grandfather died in 1996 at 85 years old and my dad Jimmy Duncan is 67 and I'm 36 and I would like to be tested for this project for our blood line so how do we go about this .

I really appreciate being put in contact with this group. My third maternal great grandmother was Lucinda Duncan. I've not been able to nail anything concrete down on her father's side. It will be exciting to participate. I've had my DNA done, and I will upload it as soon as I understand the directions more completely. Again, thank you...

My Duncan line starts in Newberry Co, SC with James Duncan (1747-1843) and Margaret Ratchford (1766-1814). I've gone back further than that but I am not as confident with that research. From SC they moved to Lumpkin County, GA. From there to Greene County in eastern TN and then to Greene County MO. That's where my dad's family lived but like most families we scattered hither and yon over the years.

I am a Duncan and I am just getting started. My dad is dead and it's hard to get ahold of my aunt and uncle's to really get information on family members. My dad's dad died when he was 10 so I don't know any of my extended Duncan family members. Any help would be appreciated.

My maternal grandmother was a Duncan, so I'd be interested in the project and where it leads to. I've taken the Ancestry DNA and provided that information to WikiTree. Let me know how I can assist

I will help where I can and make sure my line to William Robert Duncan has as many sources as I can find.
