Fox FamilyTreeDNA Project Website - Goals

Updated 7/28/2011

Our first goal was to get standard Y-DNA test data on as many men surnamed Fox as possible to see if any common thread could be found.  We now know that the Fox name has a diverse ancestry and new lines are continually being identified. Recently, however, we have been quite successful in finding matches and establishing family connections, indicating that the project has reached a certain state of maturity. While we concentrate on extending known family lines, we welcome anyone to the project who is looking for clues to their Fox ancestry and will provide adequate family documentation.

We have admitted a few with other surnames that are known cases of adoption, have possible Fox connections or are close matches to Foxes in the project.  It should be cautioned, however, that matching results with different surnames are subject to entirely different analytical rules and a close match may be pure coincidence.  There certainly is a common ancestor involved but he may have lived before the adoption of surnames.

The most efficient way to use Y-DNA testing is to start with a paper trail and a premise that can either be proven or denied.  New members are advised to select the 37 or 67 marker Y-DNA tests. For certain situations an upgrade to 67 or 111 markers may be recommended.  37 markers are required to establish a connection within a genealogical time-frame and the additional 74 markers give additional information on stable markers that may help in the analysis of deep ancestry and may help distinguish between lines of the same family group.  It must be remembered that the interpretation of results is a matter of statistical probabilities and, the more markers that match, the higher the probability of a recent common ancestor.  More markers help improve confidence limits for the prediction of time to the most recent common ancestor (TMRCA) and FTDNA’s markers 26 through 37, in particular, contain a number of markers that mutate frequently and provide a good test of a relationship. 

The group coordinator hopes to get further volunteers from descendants of Francis Fox of Wiltshire and Cornwall, England, and of Justinian Fox of Philadelphia, PA, to round out his own family study. The whole story has been told in a book by the project administrator entitled Growing with America - The Fox Family of Philadelphia, available at Xlibris.com, Amazon.com and Barnes and Noble bookstores.  The book is searchable at Amazon.com.

Since tradition has Francis Fox being related to Sir Stephen Fox, Lord Holland, and to the Earls of Ilchester, any possible male descendants of these gentlemen [such as the Fox-Strangways family] are urged to join the project. Other project members have proposed a connection to Sir Stephen Fox and it would be a real project coup if the true connection could be determined.

One Fox researcher proposes that the Henry Fox/Anne West line traces back to Harold de Vaux and his son Robert de Vaux.  They were Normans who came to Britain in 1066 with William the Conqueror.  His conclusion is based on a presumed de Vaux to Vaux to Fox name change and the fact that a direct ancestor, William Fox (1497-1559,) is found residing at Stewkley Manor, Great Missenden, a property that William Vaux (1390-1460) acquired through his wife, Maud Lucy.  An even earlier tie-in of the de Vaux family to the de Baux family of Aquitaine is given in a Vance family website. Members of the Vaux family in America are being solicited to join either the Fox or Vance projects, unfortunately without success so far.  Any Vaux who is interested would be welcomed to the Fox Project.  We have a Vaux from the same line as above who once expressed an interest in the project but has yet to take action.

We continue to look for more descendants of Francis Fox and Dorothy Kekewich, Henry Fox and Anne West, William Fox of Loudoun County, VA, Thomas Fox of Concord, MA, Jacob Fuchs of Bucks County, PA, Elijah Fox of North Carolina, Richard Fox and Hannah Williamson of Virginia, Andrew Fox of Culpepper VA and Greene Co, TN. and his wife Sarah, Thomas Fox and Mary Tunstall, John Fox and Margaret Lightfoot.   For more ancestral names, see the project groupings under Project Background, which correspond to the groupings in the Y-Results tables, where each individual is identified by his most-distant known male-line ancestor.

While the standard STR haplotype is ideal for genealogical purposes, there is a great deal of interest these days in deep ancestry – finding where those male ancestors lived thousands or many thousands of years ago.  While the Haplogroup and its primary subclades can be pretty well estimated from the STR haplotype, SNP testing is the final determinant.  New SNPs are now being discovered at a rapid rate, defining the Haplogroup tree in ever finer detail and getting closer and closer to a genealogical time frame.  Where members wish to pursue SNP testing the administrators will provide encouragement and assistance and there are many Haplogroup Projects that one can then join and learn more.

A secondary project goal, therefore, is the investigation of deep male line ancestry - particularly in Haplogroups R1b and I, where the majority of our results lie. Project Co-Administrator, Neal Fox, is a recognized expert in establishing clusters of related results, based on duplications at certain very stable markers that indicate a common founder.  He has often been able to predict the subclade of R1b and confirm this with SNP testing.  The Fox Project is in the forefront of such research, which may eventually lead to the identification of paths of migration, when certain clusters migrated to Britain and from whence they originally came.  Bear in mind, however, that this is only the direct male line and everyone has thousands of other ancestors when going back this far in time.

The project administrators also want to put all project members who have identified their most distant known male line ancestor into the Ysearch database.  This has been highly successful in recruiting new members and the database is an invaluable research tool for both genealogical and population studies.  There are now over 100 project members in Ysearch, many of whom have pedigrees listed.  Unfortunately Ysearch has not been accepting gedcoms for the last year or so but members can always add a gedcom file on their personal page at FTDNA. Bear in mind that the identity of people born after 1905 are not revealed so be sure to include birth dates for these people. Unfortunately, there are still gaps where project members have failed to cooperate and the project is now only admitting members who will supply ancestral information.

In general, the project keeps the identity of its members hidden from public view by using the most distant known ancestor and test kit number to identify them in our reports and tables. Within the project, however, the administrators feel free to name names and provide connections with other project members.


Other Types of Testing


Family Finder


While outside the realm of Surname Testing, a number of our Fox Project members have had selective full genome testing done at 23andMe.  23andMe provide a “Relative Finder” to locate close cousins in any branch of the family tree. In February 2010, Family Tree DNA began offering a competitive feature called “Family Finder”.  Fox Project members are encouraged to purchase Family Finder through the project, if at all interested.  Making connections, however, is the responsibility of the individual.  Publishing a family tree (gedcom file) and/or a good list of known family surnames and locations on one’s profile page is the absolute key to success.

Family Tree DNA has upgraded their "Family Finder" application to an Illumina chip, testing more SNPs, and you can find a link to it on your personal webpage. Family Finder is less comprehensive than Relative Finder in that chromosome Y and mtDNA are not included and no medical interpretation is provided. Currently, Relative Finder at 23andMe is less expensive. Both test the 22 autosomal chromosome pairs and chromosome X on some 1,000,000 selected sites where single nucleotide polymorphisms (SNPs) have been known to occur.  Where identical segments of sufficient length are identified between two participants on one of their chromosome pairs, an estimate of the degree of relatedness is provided and the location and length of the matching segment(s) is provided. It is then up to the two participants to find out who the common ancestor was.

Your project administrators have had some experience with both Relative Finder and Family Finder and have learned some things about both their power and their limitations:
(1)    They require intensive effort by the participants to supply and match ancestral names and locations. In this respect Family Finder could have an advantage in that Family Tree DNA participants are easier to contact and may well be more oriented towards building family relationships than 23andMe participants.  23andMe is trying to improve this situation.
(2)    Both get pretty hit or miss beyond third cousins. Testing of multiple related family members may well be helpful in achieving success.
(3)    Both males and females participate equally and the number of possible surnames increases exponentially as the generations back to the common ancestor go up.
(4)    Conversely, the percentage of your ancestors contributing to your genome goes down rapidly as the generations increase.
(5)    If successful, this effort can really pay off in new information on ancestors you knew very little about.

Our conclusion is that, while this may be of interest to some of our Fox Surname Project members and we will be happy to provide advice, it is definitely not a part of the main activities of the Fox Surname Project. Feel free to contact us, however, for more information or look on your personal webpage at FTDNA.

So far twenty members of the Fox Surname Project have signed up for Family Finder: 25549, 28579, 38430, 48348, 53477, 68367, 69617, 99981, 165969, 167994, 179015, 206501, 216976, 222791, 231195, 233233, N28014, N64076 and N69127, .  25549 and 48348 are both members of the group that are null at DYS 439.  53477 and 206501 are female Fox relatives and 167994 is an adoptee looking for Fox connections.  206501 is the aunt of 68387 – it is always a good idea to test known relatives since the locations of matching segments can provide a clue to the branch of the family where the connection may lie.


Mitochondrial DNA Testing


Similarly, while mtDNA testing (for the all female line) is available through FTDNA and results are reported on this Web Site, the administrators rely on members to interpret their own results and report any success stories to the administrators.  Basically, to achieve a comparable degree of success in matching genealogies to the 67-marker Y-DNA test, a full genome sequence (FGS) mtDNA test is required.  Since FGS results have some medical implications, they are not reported on this Website.

Results from Other Testing Laboratories


We had been encouraging all of our members to submit samples to the Sorenson Molecular Genealogy Foundation (SMGF) project at smgf.org for testing at no cost as long as a pedigree of at last 4 generations could be provided.  SMGF results took some time to be reported and are not reported directly but can be retrieved with a little detective work.  All existing Fox results (24 in all) have been identified and are being monitored by the administrators of this project.  This has enabled us to add 11 additional markers to the Y-DNA results for some of our project members.

Unfortunately, this option is no longer available since SMGF has disbanded and their results are being absorbed by Ancestry.com. Similarly Relative Genetics, a related test lab, has been taken over by Ancestry.com.  A number of Foxes tested by Relative Genetics and Ancestry.com have reported their results to the project administrators and these, as well as the SMGF results, are reported at the Fox Surname Project Supplemental Website. http://home.comcast.net/~jmfoxiii/HaplogroupSummaries.html

FTDNA offers a discounted rate to those tested by other laboratories who want to join the Fox Project and be retested.  Contact the project administrator for information.
