Elizabeth’s DNA from the Australian Line of Frazers

I recently had an email from my Austrian cousin Ros. Her 2nd cousin Elizabeth had taken a DNA test. Here is how Elizabeth fits in with the Australian group of Frazers:

I wrote a Blog about Don here. While looking at Elizabeth’s DNA matches, I noticed that Jean had a sister Kathy that had tested, so I added her to the tree. This brings us back to 1827. Here is one generation earlier:

That brings us back to 1802 and adds in Cathy and Jane. John Parker Frazer and Honora White were the ancestors of the Australian Frazer Line in purple above. Elizabeth is related to Vivien as a 1st cousin once removed. She is a 2nd cousin to Ros, Jean and Kathy and a 3rd cousin to Don. Elizabeth is a 3rd cousin once removed to her non-Australian cousins Cathy and Jane.

The Archibald/Stinson Line

Going back one more generation gets us the Archibald/Stinson Line:

Unfortunately, even at this level, I am not on the tree. My Frazers descended from two of the siblings of the Archibald that married a Stinson at the top of the tree. I suppose that would make me a double 6th cousin to Elizabeth.

Elizabeth’s Australian DNA

To simplify things, I’ll compare Elizabeth to Don, Vivien and Ros. I’ll skip Jean and Kathy because Vivien’s children got all their maternal DNA from Vivien. So Vivien’s children could not match Elizabeth any more than Vivien does.

When I compare Elizabeth to Vivien and Ros, there will roughly half a chance that some of the DNA will be from the Boots family. However, when Don matches Elizabeth, that DNA would have to be from either John Parker Frazer or Honora White.

Here is an example from Chromosome 1:

Here Elizabeth matches Don and Vivien in green in the same area. This represents DNA from John Frazer or Honora White. This match stops at about position 4M. Then Elizabeth matches Ros. One likely possibility is that the yellow match between Ros and Elizabeth above is from the Boots side.

Here is a summary of Elizabeth’s Australian Frazer DNA matches:

Here are some DNA match ranges for Elizabeth compared to Vivien, Ros and Don:

Elizabeth and Vivien share 455.9 cM which is about average for a 1st cousin once removed. Ros and Elizabeth are also about average for 2nd cousins. However, Elizabeth and Don are below average for third cousins. As, I mentioned above,  the DNA ranges start to vary more the further out the relationship is.

Elizabeth’s DNA One Step Beyond Australia


Here I added Cathy and Jane who don’t have Australian ancestors. I wrote a Blog about Cathy nearly three years ago, back in the early days of Frazer DNA Blogs. From what I can tell, Cathy is from North Carolina and Jane is from Colorado.

In the darker box, I have the Elizabeth’s Australian cousins. Elizabeth is a 3rd cousin once removed to Jane and Cathy. An average or typical amount of DNA shared for a 3rd cousin once removed is about 48 cM. As can be seen for the amounts of DNA shared with Elizabeth’s cousins, the amounts go down from right to left on the top row in the above chart. Any DNA that Elizabeth shares with Cathy and Jane would likely be from Archibald Frazer born in 1802 or his wife Catherine Parker.

Pushing Back Elizabeth’s DNA to the 1700’s

The next logical step is to look at the generation before Archibald Frazer and Catherine Parker.

This adds 11 people to the 6 we have already looked at. We are not sure when this Archibald was born, but a guess was put at 1778. This is sometimes referred to as the Stinson Line as Archibald married Ann Stinson. The light blue line on the left was put in by DNA as a likely guess. Elizabeth should be a 4th cousin once removed or 5th cousin to most of these new people.

Here is how Elizabeth matches by DNA to her more distant cousins:

Unfortunately, I didn’t list these cousins in the best order. Out of the 11 more distant cousins, Elizabeth has a DNA match with three: Michael, Ken and Susan. The chances that Elizabeth will match a 4th or 5th cousin get smaller.

Elizabeth and More Distant Frazer Cousin

The next step up for Jane goes to Archibald Frazer and Mary Lilly

This couple had four sons that had descendants with tested DNA. I am in the blue line descended from Philip and Marilee is in the pink line descended from John. The descendants of Richard are also in the Archibald/Stinson line, so they are accounted for. Here Elizabeth would be 5th cousin once removed or 6th cousins to her more distant Frazer cousins. Based on the Chances of Finding a Match Chart above, her chances of having a DNA match with these people are very small.

Here is the Philip Line:

Those in yellow are already in the Archibald/Stinson LIne. Richard in green was added due to a DNA match as a likely Philip descendant.

Here is how Elizabeth matches her more distant cousins:

Elizabeth only matches Emily and Paul. And she matches them at below the normal cutoff of 7 cM.

Elizabeth and the James Line: The Final Frontier

Here the James Line is shown in white boxes:

Elizabeth would be typically a 6th cousin once removed to a 7th cousin to these people. From the list above, Elizabeth matches two people: Mary and Janet in the 5 cM range.

Summary and Conclusions

Elizabeth’s DNA behaves in an expected manner. I traced her matches from her closest Australian cousins down to her most distant James Line Frazer cousins. At each step further out, those DNA match levels go down. Elizabeth’s DNA testing confirms the genealogy we have. It also reminded me of others that had tested that I had forgotten about.

A review of the testing of Frazer DNA over the past three years, shows how the project has grown and come together.
