ROBERT GRIFFITH & ELIZABETH HUGHES LINE
DNA Double Helix
|
Robert Griffith (1854-1913) from Bangor, Caernarvonshire and Elizabeth Hughes (1851-1934), born in Holyhead, Anglesey, were my paternal great-grandparents. Robert's ancestors were all from Bangor or the Llandegai area and Elizabeth's were from Anglesey.
Three of my 2nd cousins on this line (R.L., J.W., and G.E.), a 3rd cousin x1 removed on the Griffith-Williams line (T.J.), a 3rd cousin (J.W.), and two 4th cousins (D.S. and D.R.) on the Hughes-Thomas line, together with my father and paternal uncle, have undergone autosomal DNA testing, so I've been able to create a chromosome map, showing the genome coverage for this Griffith-Hughes line. To minimize the number of tracks, I didn't include comparisons with me, as I can't add any new segments over and above those from my father. I used Kitty Cooper's great Overlapping Segment Mapping Tool to create this. The most recent common ancestors between the pairs of individuals compared are shown in parentheses in the legend. See Here for more information on chromosome mapping and tools. |
Genome Coverage for Robert Griffith (1854-1913) and Elizabeth Hughes (1851-1934), updated 20 Apr 2015 – click to open in HTM
Click on the image of the chromosome map above (or click Here) to open it as a much clearer figure in HTML with fully functional mouse-overs, showing start and stop positions of each matching segment, the length of the segment, the pair of individuals compared, and the most recent ancestors, MRCA (also shown in parentheses in the legend of the chromosome map). This chromosome map illustrates how helpful it is having multiple family members on a line undergoing autosomal DNA testing, as everyone contributes something to the rest of the group. I thank all my relatives who have had their DNA tested and contributed to this map.
Based on autosomal testing, I've been able to verify 2 (of 4) of my 2nd great-grandparents on this branch of the family (see bowtie pedigree chart below), based on DNA matching with cousins T.F., D.S., and D.F. and as shown with the "DNA Verified" icon below (available on my Downloads tab) – I use this as the "profile picture" on My Ancestry Tree for identified DNA connections or their ancestors when I don't have a photo or signature.
For the majority of the genome coverage shown in the chromosome map, it is not known whether the segment was from Robert Griffith or Elizabeth Hughes, as most of the matching segments were with my three second cousins, and so could have been inherited from either of them. On average, approximately half of the total length of the segments above will have been from each of them. Only the matching segments with T.J. and J.W. can be identified as being Robert's (inherited from a paternal grandparent) and Elizabeth's (inherited from one of her parents), respectively.

Family Tree and Haplogroups
Pedigree Chart showing Ancestors and Descendants verified with Autosomal DNA (updated 10 Jan 2015)
Robert Griffith and Elizabeth Hughes had 4 children:
- Mary Ellen (Nell) Griffith (1889-1978), who married Eric Arnold Foster (1887-1946)
- Jane (Jennie) Catherine Griffith (1890-1970), who married Edgar John Hughes (1889-1926) – 2nd cousins R.L. and J.D. are her grandchildren
- Owen Thomas Griffith (1892-1951), who married Florence Louise Corlett (1880-1945) – they were my grandparents and died before I was born
- Elizabeth Christina ("Flossie") Griffith (1897-1963), who married Thomas R Johnson Jacobs (1902-1951)
The figure below shows the haplogroup pedigree chart for my paternal grandfather, Owen Thomas Griffith. My haplogroup pedigree chart is Here and a template for this haplogroup pedigree chart (including versions for both males and females) is available on the Downloads tab.
Haplogroup Pedigree Chart for Owen Thomas Griffith (updated 10 Jan 2015)
My father has undergone Y-DNA testing (National Geographic's Geno 2.0 and Family Tree DNA's Y-111 marker STR, and BigY testing) and his Y-DNA haplogroup is R-Z225. Because Y-DNA is inherited relatively unchanged for hundreds and thousands of years, we therefore know the others sharing this haplogroup are my paternal uncle, brother, and nephew, as well as all of Dad's patriline ancestors (father, father's father, father's father's father, etc.), who were all from Bangor, Caernarvonshire:
William Griffith is my most distant identified paternal ancestor. Unfortunately the Welsh branches of my family tree are much shorter than almost all other lines, as the universally common Welsh names make genealogy research very challenging. But hopefully DNA testing (both Y-DNA and autosomal DNA, and maybe even mitochondrial DNA) will identify other relatives and extend the Welsh lines. Griffith Line Y-DNA provides more information on Robert Griffith and his ancestors.
Thanks to my 2nd cousin, R.L., having undergone mitochondrial DNA (mtDNA) testing, we know that the maternal haplogroup of Elizabeth Hughes and her matriline ancestors and descendants is HV0d. This type of DNA is inherited by both males and females from their mother, but is only passed on by mothers to their children (so shared with anyone's mother, mother's mother, mother's mother's mother, etc.). As with autosomal DNA, we all provide others with useful information with respect to Y-DNA and mtDNA. R.L. has provided me with relevant mtDNA haplogroup information from Elizabeth Hughes, which my immediate relatives haven't inherited as we aren't on her matriline, and Dad has provided R.L. and other relatives with Y-DNA haplogroup information for the Griffith line, which they didn't inherit as they aren't on Robert Griffith's patriline. But all the cousins in the chromosome map above have helped everyone else with respect to autosomal DNA, so I hope others will test too.

- 1st great-grandfather, Thomas Griffith, Jr. (1819-1893)

- 3rd great-grandfather, William Griffith (~1760-??)

If you are related to any of the above and have either undergone DNA testing (autosomal, Y-DNA, or mtDNA) or are interested in being tested, please Contact Me, so we can share information and make additional comparisons. By comparing the autosomal DNA between multiple pairs of individuals, we may be able to fill in more of the chromosome map or be able to be more specific with identifying the DNA segments as being inherited from a more distant ancestor.
