Dengate DNA Project
In early 2006 DNA tests were carried out on three male Dengates (Wittersham Tree c.1637+), where a relationship had been established back five generations—the common ancestor being James Dengate (1764-1851). These results were then compared with three Dungate males, the result being that all six shared the same DNA link. This pointed to the name splitting into Dengate and Dungate around the year 1600. Prior to this approximate date, the name is exclusively found to be Dungate. These results point to there being a single Dengate / Dungate family, although more research is needed, in particular in proving if Wittersham Tree 2, Ticehurst Tree and Rye Tree are connected to Wittersham Tree 1.
DNA tests carried out in early 2006 between two Dungate males (with no known connection prior to the test) and two Dengate males (known to be distantly related with a shared common ancestor within 5 generations) came back with a definite, conclusive link placing the common ancestor and, therefore, where the name split between Dengate and Dungate to c.1600, confirming what many researchers have long believed. Further tests carried out in March 2008 on Dengate males from Ticehurst and Wittersham Tree 2 also proved to be connected to the others who had been tested. This lends substantial weight to the theory of there being only one Dengate / Dungate family. Any deviations from this would be caused by illegitimacy. Further Dengates and Dungates are required to take the test and the more people take part in the test, the more focused the conclusions that can be drawn in establishing the long-term history of the family.
The test is based on the Y-chromosome so that only male Dengates / Dungates can participate – it involves taking a simple one-second swab from the cheek area inside the mouth.
On a 43-marker test, you might expect, on average that just one marker would mutate every 200 years or so. The mutations that do occur enable one to trace the branches back to a common ancestor (whose name, date of birth or date of death may or may not be known). All Dungates / Dengates should have 39+ common markers.
Each 43-marker record is a haplotype. There is already sufficient knowledge of haplotypes and the places where they are concentrated to be able to say where a line probably came from even 25,000 years ago.
