More DNA results have arrived!

The results of the three DNA tests, which were taken during the Swinfield Gathering in Sydney, have now been received! What do they tell us about the members of Family 3 and the wider Swinfield genealogy?

Fortunately, all three men, Leslie Ernest from Family 3A, Raymond Francis of Family 3B and Ian George of 3C match almost exactly. They only differ at one marker out of the 37 markers at which they were compared. This tells us that they really are Swinfields and do not have an errant paternal ancestor somewhere in the past as I do!

They really are “genetic” third cousins being descendants, as is Andrew John also of Family 3A, from William Swinfield (1804-1876), the emigrant of 1848. They also match with the other English representative of Family 3, Paul Frederick, who has been tested.

Furthermore, the five testees from Family 3 match very closely with those from Families 2, 5 & 12, who also been sampled. We now have 8 Swinfields whose DNA is almost identical. This suggests very strongly that all four branches have a common origin before 1700 and that, by inference, Family 4 which descends from William Swinfield’s younger brother, John, (sadly with no known living male descendants who have the surname) also joins on to that much larger lineage.

All the tests are identical at 32 of the 37 markers tested. There are only differences at 5 markers as:

Derrick Swinfield 5F 11 10 17

Maxwell Swinfield 12 & 7 & 30 11 10 17 19 36 0
John Arnold Swinfield 2 & 9 11 10 17 18 36 1
Paul Swinfield 3 & 13 10 10 17 19 36 1
Andrew John Swinfield 3A 10 9 16 19 37 4
Leslie Ernest Swinfield 3A 10 10 16 19 36 2
Raymond Francis Swinfield 3B 10 10 16 19 36 2
Ian George Swinfield 3C 10 10 16 18 36 3

It now appears that the separate families are most likely to join up, based on the known genealogy of Family 3 and the DNA results as:

The results for those Swinfields, who have now been tested through FTDNA, can be viewed on the Swinfield Project page there. You can also read,in greater detail, what they tell us. Don't forget that is where you can also see the relationships between your male ancestors.

We now need a sample from another person on a different branch of Family 5. It would also be very useful to test members of Family 1 and Family 44 (the Swinfield-Wells branch). Those are the next goals for the genetic research into the Swinfield lineage.

  1. You will be upgrading them all to 111 markers, eventually.
