X Numbering System

I have made a “page” on my website at http://yourfamilytree.micbarnette.com/mics-tree/ which lists my lineage from myself backward through ten generations. I have also added this lineage to this page at http://micsxchromosome.micbarnette.com

 
The lineage is an Ahnentafel chart. When one creates a multi-generational pedigree chart on a genealogical computer software program it will likely use the Ahnantafel numbering system. When showing X-chromosome carrying ancestors on a multi-geneational chart. The X-Chromosome format will look much like the following two charts:

 

 

 

I am #1, my father #2, my mother #3.

 
My paternal grandfather is twice the number of my father, or, #4 and my paternal grandmother is twice my father plus 1 or #5.

 
To get the number of my grandfather’s father one would double my grandfather’s number, and so forth.

 
My maternal grandfather is twice the number of my mother or #6 and my maternal grandmother is twice my mother’s number plus 1, or, #7.

 
Likewise, to get the number of my grandmother’s father one would double my grandmother’s number, and so forth.

 
The Ahnetafel numbering system is not new. In fact, most all fan charts as seen above and multiple generational charts use the same numbering system used in my Ahnentafel chart.

 
Below, in Blue, are the Ahnentafel numbers for ancestors in each generation on a Fan Chart both a male and female would inherit from his or her mother. Remember, a male only inherits an X-chromosome from his mother.

 
In Pink are the Ahnentafel numbers for ancestors in each generation on a Fan Chart a female would inherit from her father. Remember, a female inherits an X-chromosome from her mother, as well as, one from her father.
