My Top 10 DNA Matches at Each Site - Sat, 1 May 2021

Randy Seaver’s Saturday Night Genealogy Fun challenge for this week is:

I thought I’d do that, following Randy’s template:

A) On AncestryDNA, I have 149,270 matches. My Top 10 matches are:

* First cousin, mother’s side, 1,047 cM, in tree
* First cousin, mother’s side, 914 cM, in tree
* First cousin 1x removed, mother’s side, 411 cM, in tree
* Second cousin 1x removed, father’s side, 355 cM, in tree
* Second cousin, father’s side, 202 cM, in tree
* Second cousin, 1x removed, father’s side, 183 cM, in tree

* Second cousin, mother’s side, 159 cM, in tree
* Unknown cousin, father’s side, 122 cM, not in tree
* Unknown cousin, father’s side, 117 cM, not in tree

I have 10 other relatives in my tree (total 18) who tested at Ancestry.
I have 149,252 matches who are unknown cousins who are not in my tree.

B) On 23andMe, I have 1,501 matches. My Top 10 matches are:

I have 1 other relative in my tree (total 3) who tested at MyHeritage.

I have 1 other relative in my tree (total 3) who tested at FTDNA.
I have 25,669 matches who are unknown cousins who are not in my tree.

E) On LivingDNA, I have 2,228 matches. My uncle shares 2,003 cM.
The next 9 matches share:  145, 131, 130, 129, 123, 121, 120, 118, 116.
I have 2,227 matches who are unknown cousins who are not in my tree.

F) On GEDmatch, using Tier 1 One-to-Many, I have 59,415 matches that are 7 cM or larger. My top 3 matches are:

* Uncle, father’s side, 1,918 cM, in tree
* First cousin, mother’s side, 958 cM, in tree
* First cousin 1x removed, mother’s side, 433 cM

The next 7 matches are all unknown cousins who are not in my tree with cM: 104, 94, 92, 87, 87, 84, 84.
I know I have 1 other relative in my tree (total 4) who uploaded to GEDmatch,
but I have not thoroughly checked the other 59,405 matches to see if there are any others.

G) On Geneanet, I have 763 matches. My uncle shares 1,925 cM.
The next 9 matches share: 55, 54, 53, 51, 50, 49, 49, 47, 46.
I have 762 matches who are unknown cousins who are not in my tree.

H) On Geni, I have 1,857 matches. My top 10 matches share:
164, 163, 152, 148, 147, 144, 138, 138, 135, 135.
All 1,867 matches are unknown cousins who are not in my tree.

I) At Borland Genetics, I have 862 matches. My top 3 matches are:

* my father, 1887 cM, in tree
* my mother, 1887 cM, in tree
* my uncle, 1805 cM, in tree

My next 7 matches are unknown cousins who are not in my tree with cM:
74, 61, 54, 48, 48, 47. 40. 38

Note that my father and mother’s DNA were partly assembled from my and my uncle’s DNA using the Borland Genetics tools.

What does this indicate?

* With endogamy, you get a lot of matches.
* I am unable to identify my relationship with matches as high as 122 cM at AncestryDNA and 23andMe, 141 cM at MyHeritage, and 192 cM at FTDNA.
* I have not yet found known relatives at LivingDNA, Geneanet, Geni, or Borland Genetics other than my uncle whose data I uploaded.
* I found this exercise very interesting. Compare my uncle at all sites to see how much the same person varies at different sites.
* I bet I’ve mentioned a few sites you didn’t realize you can upload your data to.

I thought it worthwhile to do my Uncle as well. He is my father’s brother, so he doesn’t share my maternal matches. Since he is a generation above me, he should average double the DNA that I do with my paternal matches, but of course he got different DNA than my father did, so that ratio should vary quite a bit for each individual match.

A) AncestryDNA – Was not tested

B) 23andMe – Was not tested

C) On MyHeritageDNA, My uncle has 21,131 matches (17% more than me). 
His top 10 matches are:

* Me, nephew, 1,994 cM, in tree
* #2 to #8 are all unknown cousins not in my tree with cM:
177, 172, 136, 133, 132, 131, 130
* #9 – Second cousin, 1x removed, 129 cM, in tree
who is my second cousin, 2x removed, 79 cM with me, not in my top 10.
* #10 – Third cousin, 121 cM, in tree
who is my third cousin, 1x removed, is not in my matchlist at MyHeritage.

D) On FamilyTreeDNA, My uncle has 30,284 matches (18% more than me).
His top match is:
* Me, nephew, 1,861 cM, in tree

His next 9 matches are all unknown cousins not in my tree with cM: 
180, 176, 173, 172, 170, 169, 167, 166, 166 

E) On LivingDNA, I logged in as my uncle, and it gave me a screen saying this: 

This was strange because long ago I uploaded his DNA, and in fact, my highest match is with my Uncle. So they do have him. The above screen would not let me go any further, so I could not check his results.

F) On GEDmatch, using Tier 1 One-to-Many, my uncle has 59,821 matches that are 7 cM or larger (0.7% more than me). His top match is:
* Me, nephew, 1,918 cM, in tree

His next 9 matches are all unknown cousins who are not in my tree with cM:
165, 136, 134, 132, 132, 130, 129, 129, 128.


G) On Geneanet, my uncle has 738 matches (3% fewer than me). His top match is me with 1,925 cM.  His next 9 matches are all unknown cousins with cM:
74, 57, 55, 54, 48, 46, 46, 46, 46

H) On Geni, I did not upload my Uncle’s DNA there.


I) At Borland Genetics, my uncle has 257 matches (70% less than me).
His top 5 matches are:

* his brother (my father), 1890 cM, in tree
* his nephew (me), 1805 cM, in tree
* his father (my grandfather), 1278 cM, in tree
* his mother (my grandmother), 99 cM, in tree
* his grandfather (my great-grandfather), 71 cM, in tree

The next 5 matches are unknown cousins who are not in my tree with cM:
64, 63, 54, 45, 45

Note that my father, grandfather, grandmother and great-grandfather’s DNA were partly assembled from my and my uncle’s DNA using the Borland Genetics tools.
