Saturday Night Genealogy Fun -- Analyze Your 3rd Great-Grandparents AncestryDNA ThruLines

  Calling all Genea-Musings Fans:

It's Saturday Night again -

Time for some more Genealogy Fun!!


Here is your assignment, should you decide to accept it (you ARE reading this, so I assume that you really want to play along - cue the Mission Impossible music!):

1)  If you have AncestryDNA ThruLines results, which set of 3rd great-grandparents has the most ThruLines? [Note:  Go to Ancestry.com home age, then "DNA" tab, then "ThruLines" tab and run your mouse over each of your ancestors to see the number of ThruLines for each ancestor].  Analyze your ThruLines from these ancestors.  Are they all "correct?"  

[If you don't have AncestryDNA, but have another DNA test provider, analyze those results for your 3rd great-grandparents.]

2)  Write your own blog post, or leave a comment on this post, or write something on Facebook.

Here's mine:


The third great-grandparents with the most ThruLines are John Rich (1790-1868) and Rebecca Hill (1790-1862) with 38 ThruLines.  This couple resided in Hilperton in Wiltshire in England.  I have 21 ThruLines through their daughter, my 2nd great-grandmother Hannah Rich (1824-1911) who married James Richman (1821-1912) and migrated to the USA in 1856.  The other 17 ThruLines are through five other children of John and Rebecca (Hill) Rich. 

Of the 17 "other" ThruLines, the highest number of centiMorgans is 108 cM in 5 segments - the relationship is 3rd cousin once removed.  The other relationships of these 17 are mostly 4th cousins or 4th cousins once removed. There are 8 ThruLines in this group that share at least 20 cM with me.  There are 3 ThruLines in those 17 that share 10 cM or less with me, and they are all likely my cousins.  

I think that 37 of the 38 ThruLines are "correct" according to my research.  The ThruLine that is "incorrect" has the wrong child connected to Hannah (Rich) Richman, but is likely related through another child of John and Rebecca (Hill) Rich.

I had not looked at ThruLines yet, so this was a nice exercise.
