SNGF--My 3rd Cousin DNA matches Descendants of 2nd Grandparents

 The Saturday Night Genealogy Fun from Randy Seaver's Genea-Musings

1)  How many autosomal DNA matches do you have descended from your eight 2nd-great-grandparents (they would be your third cousins)?  Do you know how they are related to you?  Have you corresponded with them?  Why are your numbers high or low?

2)  Share the number of your autosomal DNA matches for each of your 2GGP, and answer my questions above.

My 3rd Cousin Descendants of my Great Grandparents

I've got a lot of matches that descend from my 2nd Grandparents, but they are not all my 3rd cousins. My parents were both the next-to-youngest ones in their family, and although I am the oldest of 5, my parents didn't have children until Dad was almost 40 and Mom was almost 30.  Because of this, I have many 3C1R, 3C2R, 3C3R, and 2C1R who are descendants of my 3rd Great Grandparents. For the purpose of this exercise, I have included only the 3C from Thrulines in the first list from Ancestry.  The 2nd List from Ancestry results lists ALL of the Descendants in Thrulines(there are many more not included in the Thrulines total because they have private trees). I have also included to the right of each couple the number of matches I have marked with a DOT for that couple.

Conclusions:

I have more autosomal matches at Ancestry, and 62 Total 3rd Cousins. There are a lot of 3rd Cousins who are 1, 2, and even 3 generations removed from me as well, because of the way generations fall in my family. All of my 2nd Great Grandparents were farmers. Most had larger families, with one exception in my paternal(Jakes & Morrow) and one in my maternal(Acuff & McElroy)

I have 6 total 3rd-cousin matches at MyHeritage.  I have a few 2C1R, and 3rd cousins of different generations there as well as more distant matches.  I use the dots to sort there, which helps some.

I have very few 3rd-cousin matches at FamilyTreeDNA.  I do have a number of 2C1R there as well as more distant cousins.  I have corresponded with many of my 3rd cousins who are on my list at Ancestry.
