Are men who have some form of the Corell name all descendants of a few ancestors? Where did these ancestors live? Until very recently there was little chance that answers to these questions could be found.


Traditionally there have been just two ways for a family historian /genealogist to gather data: word of mouth, or some form of written or graphic information. Now we have a third way of connecting people “genetic genealogy”. It does not replace either of the original methods, it just adds another powerful tool to our ability to expand family knowledge. During the last ten years there has been a huge advance in the power of genetic science. As a result of these new discoveries a small group of special laboratories have been created solely to allow the extension of family trees.


This is an authenticated Coat-of-Arms which is in the homes of many of the German Corell and Correll families I have met. Sometimes the handgun in the bottom of the shield is missing. Other Coats exist, but with no evidence of validity yet discovered.

Primarily they compare the Y-Chromosomes [DNA] of living males of a given surname (or some form of that name) to determine the probability of these men having a common male ancestor somewhere in the past.  (There is another system (mtDNA) which usually follows the female line, but that is beyond our research goals.)


In July of 2002 the CORRELL DNA Genealogy Project was started.


Four of the first 5 Corrells to have their Y-DNA analyzed were men belonging to an American family with a documented history from the late1700s in America. The results show that all were, in fact, descendants of a common ancestor. This is referred to as MRCA, which stands for Most Recent Common Ancestor. He was 5 generations ago. BUT, what is even more interesting, — we have discovered that they are related to another previously unknown to us, American Correll family.  AND we have found a German relative!   All of us are seeking the unknown MRCA much farther back in time.


The fifth original participant is from another well- documented Correll line.  The Project has discovered two Germans and five Americans!    None knew of the others until the Project, and all are from large, documented families.


We now have discovered 8 family groups with 2 to 8 members.   What will we find as we add more participants?  See page 6 RESULTS.


In addition to the family groups we have identified who have the same “haplotype {if you look for the definition, click it in the left column} there are many other Correll families in America of various spellings. Some of these other families are also well documented, but to date, there has been no way to determine if they are, if fact, parts of the same larger family. And beyond the United States there are many Correll families. There are about 2000 nuclear families [husband, wife & children] families in the USA who spell the name with “rr”, and hundreds in Germany when both the “one r” & “2 r” families are counted. Some of these German families also have rather complete family histories. We know of families in Scandinavia, Ireland, England, Australia, Canada - - - plus folks with the other name spelling variations. Most of these families know little of their origin or about any connections to any of the other like, or similarly named, family groups. AND, we have mentioned here only the two most common spellings of the name!


Now, for the first time, it may be possible to “connect” many of our families through the analysis of the Y‑chromosomes (DNA) of we men who were born CORRELLs/ CORELLs/ CORYELLs/ CORIELLs/ CORILLs/ KORELLs/ CORRELLOs/ CORELLIs/ etc.
