Crawford yDNA


My brother's BigY test recently verified what I and others have believed for a long time: that my James Crawford is somehow related to the James Crawford (1758-1836) of Garrard County, KY that was married to Rebecca Anderson. These results also indicates a relationship to Edward Crawford (1762-1826) of Overton, TN.

One of my yDNA 67 matches is a descendant of William Nelson Crawford (1829-1907). I am also an autosomal DNA match with descendants of William Nelson Crawford. This descendant also shares autosomal DNA with a descendant of James Crawford (1770-1833) who married Martha Knight and with a descendant of William Crawford (1748-1809). James Crawford (1770-1833) and William Crawford (1748-1809) were both in the Garrard County, KY area at the same time as my ancestor.

A descendant of Alexander Crawford (1715-1764) is grouped in the R1b group on the Crawford project.

The researcher who is a descendant of William Crawford (1748-1809) believes that his William Crawford is a 1st cousin once removed from Alexander Crawford.

The above photo is an attempt to show how this researcher believes these various lines might be related. Note that my James Crawford line is not connected. Nor is the Edward Crawford line.

yDNA - BIG News!

In your genealogy research, have you ever suspected a relationship but never could find evidence to support your suspicions?

Well that's been the case with my James Crawford research and I now have yDNA evidence to support that suspicion!

My brothers yDNA has been placed in the R-Y88686 haplogroup. My first match was to descendants of Edward Crawford of Tennessee. Unfortunately, I haven't been able to verify that our two lines resided in the same area at the same time let alone discover a family connection.


With today's notice of a new Big Y match, I now have a match with a familiar line. The new match is a descendant of James and Rebecca (Anderson) Crawford.

Crawford yDNA

Did you know you can get a yDNA haplogroup from your Ancestry DNA? Until an administrator of the Crawford yDNA project posted directions on the Clan Crawford Association Ancestry and DNA Research Forum Facebook group, I didn't know anything about this.


To do this, one needs to download Ancestry DNA and save the ZIP file in a known location. The file needs to remain 'zipped'.

The blog post, Updated Method to Get yDNA Haplogroup from AncestryDNA Results explains the process.

The second step is to use the MorleyDNA.com Y-SNP Subclade Preditor. After giving consent for the use of the data, a screen will open to upload the zipped file containing AncestryDNA results

Once the data is uploaded, a screen will appear prompting you to prove you are not a robot and again asking for consent to use the data.

The processing is quick and opens a screen showing the results. Look for the box highlighted in green on the left side of the screen. That is the predicted haplogroup.

If you wish to share the findings with other CRAWFORD researches, you may either post your results as a comment to the Facebook post or as a comment to this blog. Please include the following information in your comment.Earliest known ancestor

  • Birthdate and place if known
  • Deathdate and place if known
  • Spouse's name
  • Copy of information in the green box on the left (your haplogroup)
If your yDNA comes back any variety of R1b, I would be very interested in seeing if our research connects.

Crawford Clan DNA Challenge

Have you had your DNA tested? If so, did DNA help you answer a question? Based on Facebook posts I've seen, it appears that DNA is helping adoptees to connect with their birth family.

In my case, I wasn't hoping to identify a close relative. Instead, I was hoping (and still am hoping) to identify my 5th great grandparents -- particularly on my dad's CRAWFORD line. It's been 3 years since I first spit in a test tube (autosomal DNA) and since my brother swabbed his cheek (yDNA). That's 3 years of working with various DNA results and few clues about this mysterious CRAWFORD grandfather.

As I'm trying to learn more about our yDNA results, so I can make sense of how we might fit in the Crawford Clan, I've come to a couple of conclusions:

  • There's too little data - I need more 5th, 6th and 7th cousins to do a yDNA test
  • Determining relationships is VERY dependent on the accuracy of BOTH of our family trees

DNA Haplogroup

Thanks to some updates to the yDNA test I manage, my Crawford line (James Crawford - born 1772, died 1854) has been assigned a new Haplogroup: R-A13336. Previously, we had been grouped in the larger R-M269 Haplogroup. According to a Crawford project administrator, I also share the Y30725 terminal SNP with another match. It is my understanding that work is still being done to determine which is older: the A13336 or the Y30725.

Left Turn

Have you ever come across a new piece of information that sends your genealogy research in a totally different direction? I'm sure you have as most of us encounter this from time to time.

Yesterday, I received such a piece of information. This wasn't a document but a DNA result - a yDNA result. Apparently, my Crawford line is its own branch with my closest Crawford match being a descendant of Edward Crawford of Overton, Tennessee.

So, one of my new goals is to try and determine how this Edward Crawford might fit in with all of my James Crawford research. With only five Edwards in my database it is a relatively unusual name. Unfortunately, Alexander and Mary (McPheeters) Crawford had a son named Edward. Thus, there will be confusion in online trees as to the parents of Edward.

In looking back thru my Kentucky research notes, I do have some data placing an Edward Crawford in Madison County, Kentucky during the time period of my James Crawford research.

In 1795, Edward Crawford was listed on the tax records for Madison County, Kentucky as a male over 21 with 2 horses and 3 cattle.
