Test results and comments for the Jefferies related to Frank William Jefferies' paternal lines.
The persons that share DNA sequences with one or more of the close family mapped on MyHeritage or GEDmatch can be seen on DNA Painter. The persons that share DNA sequences with one or more of the close family mapped on MyHeritage or GEDmatch can be seen on DNA Painter; the links to the family DNA results are on the 'DNA Test Information' page. You can expand, contract and look at individual matches as you like; the key at the side shows which of the matches are thought to be from the individual ancestral lines. You can also switch from all matches to Paternal or Maternal using the line at the bottom right under the coloured key. Persons with names between #....# are persons with known family links as well as DNA matches.
In an attempt to explore the Jefferies line back in history, I took a y-DNA test with FamilyTreeDNA at the Y700 level, the most comprehensive one can go.
Of the results FTDNA says:-
Haplogroup R-FTD1795 paternal line was formed when it branched off from the ancestor R-FGC49427 and the rest of mankind around 1500 BCE. The man who is the most recent common ancestor of this line is estimated to have been born around 1350 BCE.
So far my closest matches are 4 at 67 markers out of 700. No recognised surnames have appeared at this level nor at lower levels. However at the 37 marker level one name stands out as Longacre from an ancestor given as Anders Peterson Langacre (born 1657), with a country of origin as Sweden. This is very interesting as the new feature on Ancestry showing genetic origins of parental genome suggests Swedish/Danish links on chromosomes 2, 5 and 16 and Germanic links on chromosomes 6 & 10. The FTDNA site has a page that compares my test against DNA retrieved from archaeological discoveries and the most recent of these suggest shared DNA with persons from Scandinavian sites such as one, for example from Jutland in the Viking Denmark cultural group around 800 years before the current era (CE) with our common ancestor living 4000 years ago.
For the Germanic matches the dates are, for example, for two for persons living in the early Bronze age in Bavaria around 1800 BCE but our common ancestor lived around 2500 BCE (4500 years ago).
