Painting a DNA Match on My Mother’s Side

I recently came upon a DNA match of my mother’s that I hadn’t painted yet. I use a web site called dnapainter.com to paint DNA. In order to do that, you need:

1. DNA matches
2. Yotu have to be pretty sure you have a common ancestor with those DNA matches that you can identify

Here is how my Mom is painted so far:

 

This shows my Mom to be 24% painted. That means that I have found DNA matches with most likely identifiable common ancestors for about one quarter of her autosomal DNA. However, I am missing a DNA match on my Mom’s Chromosome 22. In addition, I have no paternal matches on my mom’s Chromosome 4. The paternal side as shown above is the top blue side.

My Mom’s New Match – Ingrid

Actually my mom’s match is not really new. The match’s sister was going to add her results to Gedmatch.com, but never got around to it. Here is a Rathfelder Chart where I just added Ingrid:

By this chart, Astrid and Ingrid are 2nd cousins once removed to my mother. Here is Ingrid’s tree:

We both have slightly different trees. I wrote a Blog here in 2016 about Wilhemine. I may have written others also.

Common Ancestral DNA

I have at DNA Painter, that my mom’s common ancestors with Astrid are Rathfelder and Bittenbinder. That also agrees with Ancestry.com:

The crazy thing about this connection is that it shows two brothers with the same name. Believe it or not, I have this from a published document. That means that I have to change my chart.

That’s a pretty big change. Now my Mom is a fourth cousin with Astrid and Ingrid. With the amount of DNA shared between my mom and Astrid, Ancestry says they have a 4% chance of being fourth cousins:

However, there is a good chance that they are related on additional lines due to intermarriage within the Colony of Hirschenhof where these ancestors lived.

Here is Astrid’s DNA at DNA painter (as she matches my Mom).

Here is how Ingrid matches my mom at Family Tree DNA:

Some of these matches are below 7 cM and by default, DNA Painter does not add matches less than 7 cM.

Here is the DNA that Ingrid adds:

Ingrid matches my Mom at similar places as her sister Astrid. However, Ingrid adds some DNA that on Chromosome 19. Due to the nature of DNA mapping, the largest matches are first and the newest ones are usually smaller.

Painting My Match with Ingrid

I can do the same for me. Here is my match with Astrid on DNA Painter:

Every time you go through a generation, some specific DNA is lost or diluted. Also my representation of Rathfelder and Bittenbinder has a pink background as they are on my Maternal side. For my mom, they are on her Paternal side.

This shows that Ingrid didn’t add anything new for me:

Ingrid is in the grey and Astrid in green.
