About the study

 I have been studying the moon line for about 50 years.  I started my one name approach for the moon line 5 years ago.  I have started in Lancashire, England where my ancestors originated.  I have data bases for all the Moon's in England, Scotland, Wales, Ireland, and Jamaica. The Moon's from Lancashire, emigrated throughout the world, Australia, Scotland, Wales, Ireland, Pennsylvania, Virginia and Jamaica.




Name origin

The Moon name is a multi-origin name. There are at least 10 different lines of Moon's in the world. shows the DNA breakdown for those lines.  


Variant Names

Moon, Mohun, Moon and Moun are the most common.

Name frequency

The highest concentration of moons in the 1881 census compared to Y-DNA of the Moon name done by Living DNA.

Comparison of 1881 Census and Y-DNA for the Moon name



The study sponsors one DNA project located at Family TreeDNA (Mohun).  It is my hope to find out how many of the Moon’s in England are from a common origin. The moons supposedly came to England with William the Conqueror and the name at that time was Mohun.  I have not been able to find any sources to prove this claim.  I have resorted to YDNA to prove or disprove the claim.  There are many great matches with Moons in the United States but few matches with anyone in Great Britain.  I would like to encourage individuals from Great Britain to do a Y-DNA study at Family TreeDNA and see if our lines are related. When I find a Mohun line with YDNA we will be able to compare the Moon DNA and see if there are any lines that descend from Mohun.

The DNA distribution map above shows Moons in all of England are related.  More Y-DNA is needed to prove those relationships. Y-DNA is needed from every county in England.   If you have any curiosity about where the Moon name originated and who is related to whome then please test.  Go to the Mohun page on Family TreeDNA and near the bottom there is a discount for Y37 DNA.
