Which side

How do tell in your family finder which matches are for the mother and which are for the father?
Thanks

The easiest way is to test the mother and father and compare the "in common with's." Otherwise you just have to figure it out.

You can't tell from DNA alone, unless you get other relatives to test. If your parents were from different ethnic backgrounds, you can make some educated guesses.

lkocanda,
In my case my mother is deceased, I tested my father, my mother's sister.

I do not have matches 'in common with' my father, but then the matches 'in common with my aunt were less than the total matches I have.

Then I tested a first cousin of my mother.

The puzzle started to fit in, some people match me and my aunt, others match me and the cousin, some match my aunt and the cousin, so it was clear which ones come from my maternal grandmother's side (the cousin is from that line)

I still have matches that can not be classified with none 'in common with', but that does not rule out that they are from my maternal grandfather or my maternal grandmother. I am eager in next months to get some matches in common with my father.

So you could try to test cousins coming from either of the sides and could get some mutual matches. For sure there will be people that do not match any of the cousins.... but it is worth testing cousins...

This is really where Ancestry.com has helped me. If you take their test and tie it to a tree, matches also attached to a tree will show the common ancestor. I have found multiple distant cousins this way.

If your parents have similar ethnic backgrounds, beyond a 3rd cousin you may not be able to identify which side.

In my case my mother has tested but father's deceased. My father's first cousin and a different 1st cousin's granddaughter on his mother's side have tested. On my father's father's side my 2nd cousin's daughter, and my 3rd cousin have tested.

About 7% of my mother's matches are "in common with" at least one my close cousins on my father's side.

Beware of AncestryDNA's hints. I have a couple of hints that show a common ancestor on my mother's side, but the people with the hints aren't on my mother's relative list.

Interesting. So far all of the common ancestors have been in my tree. I'll watch for that, though.


Thanks!

Ikocanda,

The x-chromosome is sometimes useful in determining which side your matches come from. (x-chromosome, not mitochondrial DNA!!)

If you are male, anybody who matches you on the x-chromosome will be on your mother's side of the family. If you are female, it might be advisable to test a brother.

You will have to upload your raw data to gedmatch.com in order to see your
x-chromosome matches. FTDNA has promised an X-browser but has yet to deliver.
