I looked at my sister Heidi’s AncestryDNA clusters here<\/a> and my brother Jon’s here. I used the bottom level of 25 cM and top-level of 600 cM for their matches. This resulted in 20 clusters for Jon and 23 clusters for Heidi. This is what my clusters look like at those same levels:<\/p>\n

\"\"<\/a><\/p>\n

I have 37 clusters. These clusters are proportional to the number of 4th cousins or closer that we have a AncestryDNA.<\/p>\n

\"\"<\/a><\/p>\n

In my previous tries at looking at my clusters, I chose match levels that resulted in first 5 clusters and then 76 clusters. 37 clusters seems like a good number, plus it will give me a good comparison to my two siblings.<\/p>\n

Starting to Identify My Clusters<\/h2>\n

The thought behind clusters is that a group of clusters probably indicates a group of ancestors that are all along a particular line. I have sorted my clusters by DNA match. I have my top match in the cluster followed by the match amount in cM. Then I have the cluster number, my grandparent line and then common ancestors or other notes:<\/p>\n

\"\"<\/a><\/p>\n

I continued the cluster numbers down in the order of their match levels. Cluster 17 is out-of-order in a sense. There are only 4 people in the Cluster 17 and one is my maternal 1st cousin’s daughter. So those matches could be on either side of my maternal grandparents.<\/p>\n

Cluster 10 and Gladys<\/h3>\n

Here is how I am related to Gladys:<\/p>\n

\"\"<\/a><\/p>\n

That’s assuming that I have this tree right. Gladys is my third cousin, once removed. We have a double Frazer ancestry. That makes me wonder how I am related to the other people in Cluster 10:<\/p>\n

\"\"<\/a><\/p>\n

Ancestry shows me at the same relationship to Gladys as with the rest of the group. However, I’m not so sure about that.<\/p>\n

I tried building out Debra’s tree and found some Irish ancestors:<\/p>\n

\"\"<\/a><\/p>\n

Little and Burns were both from Ireland if I drew Debra’s tree correctly.<\/p>\n

Here is John’s tree:<\/p>\n

\"\"<\/a><\/p>\n

John appears to have two Burns Lines in his tree. So that is something to keep in mind in case this is more than a coincidence.<\/p>\n

\"\"<\/a><\/p>\n

It looks like my top 5-10 clusters are all on the Frazer side.<\/p>\n

Some Relatives from Russia?<\/h3>\n

\"\"<\/a><\/p>\n

My Rathfelder ancestors lived in a German Colony in Latvia. In Cluster 11, I have some relatives that were from a German Colony in Russia about 1,000 miles away from Latvia. I have read of at least one connection between the two colonies. These are my top 20 clusters. I seem to favor the Frazer side as more than half of the clusters are Frazer clusters.<\/p>\n

Diving Further Into the Unknown Clusters<\/h3>\n

The next Cluster is 30. One of the two people in that Cluster, Howard, has a tree with this person:<\/p>\n

\"\"<\/a><\/p>\n

This looks like the same Hannah that I have in my tree:<\/p>\n

\"\"<\/a><\/p>\n

Hannah’s grandparents would be Howard and my common ancestors: Samuel Snell and Mary Head.<\/p>\n

Cluster 16 and a New Ancestor Discovery<\/h3>\n

\"\"<\/a><\/p>\n

I can see this from this table from AutoCluster:<\/p>\n

\"\"<\/a><\/p>\n

A note that I had put under my AncestryDNA match Bobby turned out to be helpful.<\/p>\n

\"\"<\/a><\/p>\n

I have no idea who Seymore is and have no known ancestors in this area of the country. I suspect that we may have common ancestors in England or Ireland. From what I can tell, this match is on my Frazer grandparent side.<\/p>\n

My Last Seven Clusters<\/h3>\n

Here is a summary of all my clusters:<\/p>\n

\"\"<\/a><\/p>\n

My Clusters Compared to My Brother’s and Sisters’ Clusters<\/h2>\n

I wold like to see how my clusters compare to my brother Jon’s and my sister Heidi’s. It looks like my matches tend to the Frazer side. The process was a bit annoying, so I took the data files into MS Access and compared them there. I came out with this comparison:<\/p>\n

\"\"<\/a><\/p>\n

This shows where my clusters are equivalent to Jon’s or Heidi’s.<\/p>\n

Here is the same chart by match size:<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

I match Cheryl at 69.1 cM but her Cluster has no match with Jon or Heidi.<\/p>\n

This shows that I split Heidi and Jon’s Cluster 1 into two. They are now my Clusters 2 and 1. Likewise, I split Jon’s Cluster 20 and Heidi’s Cluster 15 in two. They are my Clusters 21 and 15. One theory is that I am related on both common ancestral lines and Heiid and Jon are related on only one. My assumption is that my Cluster 15 is related to my Cluster 21. I split Jon’s Cluster 6 into my Clusters 10 and 28. However, I don’t match Heidi on my Cluster 28. I had already determined that My Clusters 10 ane 28 involved the same Frazer couple.<\/p>\n

My maternal Cluster 17 is described by Jon’s cluster 8 and Heidi’s Cluster 14. These are not helpful because they are on my mother’s maternal and paternal sides. I need to lower the thresholds so Taylor does not show in the matches. She is a 1st cousin once removed, so she is related on both of my maternal grandparent sides.<\/p>\n

Summary and Conclusions<\/h2>\n
