RESEARCH STATUS & PROJECT HIGHLIGHTS
· GRACE Y-DNA Project:
Phase One - Completed in April 2010, proving this GRACE family male genetic haplotype. Any direct-descendant GRACE male belonging to this tree can check his own haplotype against the 66/67 genetic marker match provided by this researcher & a 3rd cousin’s Y-DNA. A total of 111 markers are available for comparison. Genetically, Jeremiah’s Y-DNA is proven.
Phase Two - Completed in 2015, following extensive research of the GRACE family line connected to Stacey GRACE of Waddesdon, Buckinghamshire & Chelmsford, Essex (s/o Thomas GRACE Jr & Mary ABRAHAM), geographically the nearest GRACE family to the recorded origins of Jeremiah. Y-DNA tests of living male descendants on this line have ruled out any genetic connection to the family of Jeremiah. Like most GRACE lines (including those of Irish decent), the Buckinghamshire family are genetic type “I”, rather than type “R” for Jeremiah. This is genetic evidence supports the evidence so far revealed that the Family of Jeremiah GRACE is not a genetic GRACE family, but an orphan or illegitimate line.
Phase Three – Ongoing. With Jeremiah’s haplotype being registered on all Y-DNA databases seeking any familial (surname) match. Should this ever materialise, investigations will resume in the Colchester area of Essex to find potential living descendants who could provide a genetic match. Any Y-DNA results from GRICE descendants from the Colchester area is of interest (none currently registered). Despite the increasing interest in genetic genealogy, there are no close matches at any level to any surname that can be considered within a historic timeframe. In 2017, a report by English Origenes has been received but remains an unsatisfactory piece of work. The author (Dr. Tyrone Bowes) declined to enter into discussions and did not provide references for the sources claimed in the report, despite several requests. My critique of the report is available. Some initial commentary was also provided on Facebook.
In the wider research on Y-DNA, Jeremiah’s haplotype has been registered with a number of groups in FTDNA including the R1b-U106 and smaller group looking into CTS10893, based on a few SNP tests. R1b-U106 is a patrilineal descended family that appears to descend from an ancestral R1b group located among or near the Yamnaya culture, north of the Black Sea area. The group rose to significance in southern Germany and the surrounding areas about 3000 BC. Although U106 is found all over Europe, and in countries that Europeans have migrated to, it is most significant in Germany and surrounding countries, Scandinavia, and Britain. CTS10893 is sub-group of R1b-U106:
In the above chart, "ybp" indicates years before present when the mutation defining the branch took place. (510=15) indicates that anyone testing 111 markers will find DYS510 (the 108th marker) repeat count = 15 if they are CTS10893. CTS10893 is also referred to as a Saxon marker and was probably brought to England by Anglo-Saxon settlers. On the following map (Jeremiah’s birth location, marked “21”) shows the nearest genetic cousins with the same marker:
Unfortunately, even within the CTS10893 family current genetic distances to other testers indicate that we are no nearer to finding close matches that may indicates Jeremiah’s original paternal surname:
