I was wondering today if I had missed any painting of my X Chromosome.
My Current X Chromosome Painting
Right now I have this:
The Blue is on my mother’s mother’s side. My grandmother was Emma Lentz, but I put the assignment back another generation to her parents. The blue is based on my first Cousin Cindy’s results. The orange is on my mother’s father’s side. This is based on a second cousin match. She lives in Latvia.
Cousin Rusty’s Match
I was wondering if my cousin Rusty would add anything:
Cindy got the X that matches my family from her dad. He in turn, got his from his mom Emma Lentz. With Rusty, we match on our mother’s sides. Our mother’s got their X Chromosomes from both of their parents.
Comparing My X Chromosome with Cindy and Rusty
When I compare my X Chromosome with Rusty and Cindy, I get this:
Compare that to my Chromosome mapping with Visual Phasing:
The places where I match Rusty is where I am mapped to my Rathfelder grandfather. The place where I match Cindy, is where I am mapped to my Lentz grandmother. The places where my X Chromosome matches go back and forth between Rusty and Cindy are the same places my DNA goes from Rathfelder to Lentz and back again. Based on this, I would say that all my X chromosome match with Rusty is from Alexander Rathfelder. Further, I could say that Alexander got all his X Chromosome from his mother Maria Gangnus. Further, I could say that she got her DNA from her two parents Johann Philipp Gangnus born 1829 and Jacobine Lutke.
Painting My Gangnus/Lutke X DNA
Before I paint in new DNA, I check my current stats:
This shows that currently, I am 36% mapped overall, but only 25% mapped or painted on my maternal side.
Here is the new look:
The New Stats
My maternal side went up 3%. I added over 100 cM of DNA with Rusty.
Overall, I went up 1%.
Checking My Work
Based on how I match Cindy and Rusty, I would not think that Rusty and Cindy would have much of a match on the X Chromosome:
The spot where Rusty and Cindy match each other is same area where I am missing a match on my X Chromosome. I can guess what this means. I am mapped to Lentz in this region. Everywhere I match Rusty, I match him on Rathfelder. I match Cindy in this region except for one segment. My assumption, then, is that Cindy has a small Rathfelder segment in the middle of her Lentz DNA. There are probably other explanations, but that is the one I thought of.
Any Practical Application to This?
Yes and no. No in that I already had this information. Yes, in that this makes me more aware of what I had.
X Chromosome Matches at Gedmatch
My first X Chromosome match that I don’t already know and who has a tree is Alice.
Alice has no autosomal match with me.
Scanning her tree, I see a Faunce name:
Elizabeth Faunce is Alice’s mother’s mother’s mother’s father’s mother. That fits in well with X Inheritance.
Here is my mother’s tree:
Here I have a Faunce at my mother’s mother’s father’s mother’s mother level. She is Catherine Faunce born in 1805. Do you think the families match up?
Alice’s Tree
I see that I already had a tree for Alice. But I didn’t go far enough.
I had gone out to Elizabeth Faunce. Her father is believed to be George Faunce who was born in 1776 in Philadelphia and died there in 1838. My ancestor Jacob Faunce was born in 1774. He lived in Kensington which is part of present-day :Philadelphia and died in 1854. From what I can tell, these two Faunce men were not brothers. Too bad. So close.
Summary and Conclusions
- I realized that I could map my first cousin’s X Chromosome matches to DNA Painter.
- This got me thinking about DNA X Chromosome matches
- I tracked down an X Chromosome match’s ancestry. I got back to the same city and the same last name but couldn’t make the connection. This seems like too much of a coincidence to me.
